589d636b	2020-04-22T14:57:06	Fixed rare crash when creating an X11 window
b6afbe63	2020-04-07T09:38:57	Added SDL_log.h to SDL_internal.h so logging is available everywhere
1b82606e	2020-02-17T16:11:18	x11: Wait a bit in SDL_SetWindowSize() to see if window manager vetoed change. Same idea as the fix for Bugzilla #4646. Fixes Bugzilla #4727.
e7315225	2020-02-17T15:02:37	x11: Don't delay an extra 10ms if we were just going to break out of the loop.
367a8b97	2020-02-17T15:00:02	x11: Don't wait for the window to move if it's already in the place we want it.
d1df3437	2020-02-14T13:17:18	x11: SDL_SetWindowPosition should try to wait for the window manager. Wait up to 100 milliseconds, since the window manager might alter or outright veto the window change...or not respond at all. In a well-functioning system, though, this should help make sure that SDL_SetWindowPosition's results match reality. Fixes Bugzilla #4646.
4b585e75	2020-02-03T08:06:52	Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about desktop OpenGL on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that requires the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

b1539c4c	2019-11-16T22:35:48	Fixed bug 4819 - Attempting to create an OpenGL ES context with unachievable MSAA parameters under X11 dooms the program Solra Bizna I have written a program that, in the event that the user requests more MSAA samples than their hardware supports, attempts to gracefully fall back to the best MSAA available. This code works with my conventional OpenGL renderer, but if I change nothing about the code except to make it request an OpenGL ES profile instead, Xlib kills the program with an error that looks like: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x5c00008 Serial number of failed request: 188 Current serial number in output stream: 193 To trigger the bug, attempt to create a window with the SDL_WINDOW_OPENGL flag, with SDL_GL_CONTEXT_PROFILE_MASK set to SDL_GL_CONTEXT_PROFILE_ES, and with SDL_GL_MULTISAMPLESAMPLES set to any unsupported value. SDL_CreateWindow properly returns NULL, but at this point the program is already doomed. Xlib will shortly terminate the program with an error. Calling SDL_CreateWindow again will immediately trigger this termination. I have attached a skeletal program that reproduces this bug for me. Replacing SDL_GL_CONTEXT_PROFILE_ES with SDL_GL_CONTEXT_PROFILE_COMPATIBILITY avoids the bug (but, obviously, doesn't create an OpenGL ES context). As I suspected, the problem was with XDestroyWindow being called twice on the same window. The X11_CreateWindow function in src/video/x11/SDL_x11window.c calls SetupWindowData. If initialization fails after that point, XDestroyWindow gets called on the window by a subsequent call to X11_DestroyWindow. But, later in the same function, iff a GLES context is requested and initializing it fails, X11_XDestroyWindow (which wraps XDestroyWindow) is manually called. Shortly after, the intended call to X11_DestroyWindow occurs, which attempts to destroy the same window again. Boom. (The above confusing summary involves three separate, similarly-named functions: XDestroyWindow, X11_DestroyWindow, X11_XDestroyWindow) I have attached a simple patch that removes the redundant X11_XDestroyWindow calls. I've tested that XDestroyWindow still gets called for the windows in question, and that it only gets called once.
c0255be4	2019-10-26T23:58:55	x11: check if the X server honored our XMoveWindow() call (thanks, R.E. Rust!). This can happen if a window is still grabbed when we try to move it, or if the X11 ecosystem is just in a bad mood, I guess. This makes sure that SDL will report the correct position for a window; otherwise, SDL_GetWindowPosition will just report whatever the last SDL_SetWindowPosition call requested, even if the window didn't actually move. Fixes Bugzilla #4646.
e5580e18	2019-09-04T09:27:58	x11: add a hint to force the VisualID used when creating a window.

e061a92d	2018-08-02T16:03:47	Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.
8ddebfa0	2018-02-16T10:23:10	Fixed bug 4085 - X11: Allow configuring _NET_WM_BYPASS_COMPOSITOR through SDL hints Callum McGing This patch allows the user to disable the behaviour that blocks the compositor through a new hint: SDL_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR. This allows tools or other windowed applications to behave properly under KWin.

f5a38f23	2017-08-21T00:42:06	x11: specify event mask for buttons when grabbing pointer (thanks, Stas!). This fixes a strange corner case (notes appended below), and should be safe to do anyhow. Fixes Bugzilla #3674. "I did more tests. It appears the bug only happens if there is another window on the screen that has "always on top" property. For me it is xawtv - it is always opened in a screen corner. Closing xawtv or removing "always on top" property from it makes the problem to go away. Plus, it doesn't appear like the buttons are not delivered at all. It appears that instead the button presses are delivered on some mouse positions, but not delivered when you move the mouse to other part of the window... So this is really weird and is likely somewhere deep in the Xorg. Maybe somehow it happens that the cursor is actually above the xawtv window, but, because my app uses grab, it is not visible there, and in that case the events are not delivered to my app? But with my patch the button events are always delivered flawlessly, it seems. Hmm, and that indeed seems to explain my problem: if the mask is set properly and my app uses grab, then, even if the mouse is above some other window, the events would still be delivered to the grabbing app, which is what actually wanted because my app uses relative mouse mode, so it doesn't know the pointer can cross some other window (my app draws the pointer itself). So my current theory is that my patch only enforces the mouse grab, which otherwise can be tricked by some other window preventing the button events delivery (but motion events are still delivered via xinput2, which makes it all look very obscure)."
362d5496	2017-08-14T10:28:47	Fixed bug 2500 - X11: SDL tries (and fails) to hide foreign windows Alvin I'm interested in this bug as well. I have experienced it when trying to embed an SDL_Window into a FLTK application. To do this, I create a FLTK window (window inside a window - think video player) and then use SDL_CreateWindowFrom() on the inner most window's Xlib Window. After which, I create a renderer. In my situation I am using the FLTK GUI toolkit. What I have experienced is that the SDL_CreateRender() will recreate the window in order to properly setup OpenGL capability. As part of this process, the window is hidden and a call is executed that waits indefinitely for an acknowledgement that the window was indeed unmapped. This is where my program hangs. Please correct me if I am wrong, but should SDL2 not make Xlib calls that effect the Xlib Window in this situation (e.g. When SDL_CreateWindowFrom() is used)? The toolkit being used typically assumes responsibility and, I presume, tracks all Xlib Windows it creates. On line src/video/SDL_video.c:1372 the comment associated with setting SDL_WINDOW_FOREIGN reads: / Can't destroy and re-create foreign windows, hrm / Since I do not know the reason for hiding the window in the first place, the attached patch simply does not wait for a response when X11_XWithdrawWindow() and X11_XMapRaised() are issued by X11_HideWindow() and X11_ShowWindow(), respectively. I presume that the GUI toolkit (GTK, FLTK, etc.) has or will consume the acknowledging event as it is managing the Xlib Window (or it thinks it is). I have tested the patch against hg 5c645d037de2 and I have successfully tested: Embedding the SDL_Window inside a FLTK application. * Calling SDL_SetWindowSize() when FLTK resizes the window (e.g. dragging cursor on the edge of the window). * Filling the renderer's default target blue and drawing a red fill square at the centre (exciting, I know!) * Calling SDL_Quit() when the application terminates I do not receive any Xlib erorr messages (BadWindow, etc.) in any of those situations.
177f19af	2017-07-20T10:52:43	Fixed bug 3410 - SDL_WINDOW_HIDDEN flag is inaccurate. Jason Wyatt After hiding the window, SDL_WINDOW_HIDDEN/SDL_WINDOW_SHOWN flags on a window are correctly updated. However on the next SDL_PumpEvents, they are set incorrectly. This appears to be because X11_GetNetWMState does not check whether the _NET_WM_STATE property exists (it shouldn't on unmapped windows, see https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html#idm140130317598336). This results in an empty list of atoms for the state, which would imply that the window is not hidden. (Seen on Fedora 24, Gnome) -- Dan Ginsburg More details on my proposed patch: I am on Kubuntu 16.04.2. I ran into this same bug, but with Jason's patch I found that actualType != None was true so the SDL_WINDOW_HIDDEN would still not be set. My fix instead is to explicitly check for whether the window is unmapped rather than relying on the returned values in XGetWindowProperty.
c80c3419	2017-07-04T20:44:07	x11: pass a long to XChangeProperty, not an int. The Xlib documentation demands that 32-bit values here be passed in a long, even when long itself isn't a 32-bit value. Otherwise libx11 might read memory incorrectly. Fixes Bugzilla #3692.

66555f61	2017-04-06T13:27:48	SDL - attempt to fix https://github.com/ValveSoftware/Dota-2/issues/1199 of mouse not locking in Dota. This fix is proposed by Ryan Gordon (increase timeout in X11_SetWindowGrab from 250ms to 5000ms). I'm going to integrate to source2 and ship it to dota customers. If it works, SamL will upsteam it to SDL.
266816b4	2017-03-26T21:00:19	Removed newlines from error messages.
a52d48c5	2017-01-10T08:54:33	Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11 Mark Callow The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile: - Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can say to use the OpenGL ES driver & EGL rather than the Open GL driver. (For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects. With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

f647dfe8	2016-03-04T19:41:16	x11: Fix a few more XMoveWindow() calls to adjust for border size. Also, fix my inability to do basic math ('+' should have been '-').
02f49fdb	2016-03-04T18:47:19	x11: Deal with window borders better. - Cache the _NET_FRAME_EXTENTS data locally, so we don't have to query the X server for them (instead, we update our cached data when PropertyNotify events alert us to a change). - Use our cached extents for X11_GetWindowBordersSize(), so it's a fast call. - Window position was meant to refer to the client area, not the window decorations, so adjust appropriately when getting/setting the position.
2436ca20	2016-02-20T01:03:39	x11: better fix for the previous commit's fullscreen vs maximized issue.
a4627c5e	2016-02-20T00:44:42	x11: Don't mess with fullscreen vs maximized window state on unmapped windows.
45407d0e	2016-02-15T21:49:09	x11: Removed an assert. This assert triggers when run under XMonad. It's safe to pass a zero here anyhow, as this will still work "well enough" and the original problem--GNOME printing a warning message--is still fixed because GNOME's window manager gives us a chance to grab a non-zero user-time value before this code is run.
3bdaf4c6	2016-01-05T02:46:10	Added SDL_SetWindowOpacity() and SDL_GetWindowOpacity(). This is currently implemented for X11, Cocoa, Windows, and DirectFB. This patch is based on work in Unreal Engine 4's fork of SDL, compliments of Epic Games.

dc532c70	2016-01-05T02:27:50	Added SDL_WINDOWEVENT_TAKE_FOCUS. This is for corner cases where a multi-window app is activated and wants to make a decision about where focus should go. This patch came from Unreal Engine 4's fork of SDL, compliments of Epic Games.
f9af0c03	2016-01-05T02:27:26	x11: Put a matching window_group wmhint on every window created. This is useful to the Window Manager, so it can know to associate multiple SDL windows with a single app.
f2defe5e	2016-01-05T01:30:40	Added special window type flags. Specifically: always on top, skip taskbar, tooltip, utility, and popup menu. This is currently only implemented for X11. This patch is based on work in Unreal Engine 4's fork of SDL, compliments of Epic Games.

Unity's window manager is (legitimately, since it moves the client window's position) sending one, and SDL was incorrectly trying to mask it out. Other window managers (KWin, apparently) don't move the window and would hang here indefinitely. Fixes Bugzilla #3052.

0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

b88ca1b4	2015-02-10T16:28:56	the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

d44f3922	2014-07-07T10:33:32	Fixed bug 2629 - Mac: crash when calling SDL_DestroyWindow with an active OpenGL context Alex Szpakowski Since this commit https://hg.libsdl.org/SDL/rev/59b543340d63 , calling SDL_DestroyWindow will crash the program if the window has an active OpenGL context. This is because the Cocoa_DestroyWindow code sets the window's driverdata to NULL and then calls [context setWindow:NULL], which tries to access the window's driverdata, resulting in a null pointer dereference. I have attached a patch which fixes the issue by moving the line which sets the driverdata to NULL to after the lines which call functions that use the driverdata pointer.
b29740b8	2014-06-25T17:06:12	Merged Ryan's SDL-gui-backend branch. Adds three APIs, and implements them on X11, Cocoa, and Windows: - SDL_CaptureMouse() - SDL_GetGlobalMouseState() - SDL_SetWindowHitTest()

98c03f39	2014-05-28T01:22:47	Changed drag area API to a hit-testing API. There were several good arguments for this: it's how Windows works with WM_NCHITTEST, SDL doesn't need to manage a list of rects, it allows more control over the regions (how do you use rects to cleanly surround a circular button?), the callback can be more optimized than a iterating a list of rects, and you don't have to send an updated list of rects whenever the window resizes or layout changes.

Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about *desktop OpenGL* on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that *requires* the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

Fixed bug 4819 - Attempting to create an OpenGL ES context with unachievable MSAA parameters under X11 dooms the program Solra Bizna I have written a program that, in the event that the user requests more MSAA samples than their hardware supports, attempts to gracefully fall back to the best MSAA available. This code works with my conventional OpenGL renderer, but if I change nothing about the code except to make it request an OpenGL ES profile instead, Xlib kills the program with an error that looks like: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x5c00008 Serial number of failed request: 188 Current serial number in output stream: 193 To trigger the bug, attempt to create a window with the SDL_WINDOW_OPENGL flag, with SDL_GL_CONTEXT_PROFILE_MASK set to SDL_GL_CONTEXT_PROFILE_ES, and with SDL_GL_MULTISAMPLESAMPLES set to any unsupported value. SDL_CreateWindow properly returns NULL, but at this point the program is already doomed. Xlib will shortly terminate the program with an error. Calling SDL_CreateWindow again will immediately trigger this termination. I have attached a skeletal program that reproduces this bug for me. Replacing SDL_GL_CONTEXT_PROFILE_ES with SDL_GL_CONTEXT_PROFILE_COMPATIBILITY avoids the bug (but, obviously, doesn't create an OpenGL ES context). As I suspected, the problem was with XDestroyWindow being called twice on the same window. The X11_CreateWindow function in src/video/x11/SDL_x11window.c calls SetupWindowData. If initialization fails after that point, XDestroyWindow gets called on the window by a subsequent call to X11_DestroyWindow. But, later in the same function, iff a GLES context is requested and initializing it fails, X11_XDestroyWindow (which wraps XDestroyWindow) is manually called. Shortly after, the intended call to X11_DestroyWindow occurs, which attempts to destroy the same window again. Boom. (The above confusing summary involves three separate, similarly-named functions: XDestroyWindow, X11_DestroyWindow, X11_XDestroyWindow) I have attached a simple patch that removes the redundant X11_XDestroyWindow calls. I've tested that XDestroyWindow still gets called for the windows in question, and that it only gets called once.

x11: check if the X server honored our XMoveWindow() call (thanks, R.E. Rust!). This can happen if a window is still grabbed when we try to move it, or if the X11 ecosystem is just in a bad mood, I guess. This makes sure that SDL will report the correct position for a window; otherwise, SDL_GetWindowPosition will just report whatever the last SDL_SetWindowPosition call requested, even if the window didn't actually move. Fixes Bugzilla #4646.

Some drag'and'drop improvements. First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.

x11: specify event mask for buttons when grabbing pointer (thanks, Stas!). This fixes a strange corner case (notes appended below), and should be safe to do anyhow. Fixes Bugzilla #3674. "I did more tests. It appears the bug only happens if there is another window on the screen that has "always on top" property. For me it is xawtv - it is always opened in a screen corner. Closing xawtv or removing "always on top" property from it makes the problem to go away. Plus, it doesn't appear like the buttons are not delivered at all. It appears that instead the button presses are delivered on some mouse positions, but not delivered when you move the mouse to other part of the window... So this is really weird and is likely somewhere deep in the Xorg. Maybe somehow it happens that the cursor is actually above the xawtv window, but, because my app uses grab, it is not visible there, and in that case the events are not delivered to my app? But with my patch the button events are always delivered flawlessly, it seems. Hmm, and that indeed seems to explain my problem: if the mask is set properly and my app uses grab, then, even if the mouse is above some other window, the events would still be delivered to the grabbing app, which is what actually wanted because my app uses relative mouse mode, so it doesn't know the pointer can cross some other window (my app draws the pointer itself). So my current theory is that my patch only enforces the mouse grab, which otherwise can be tricked by some other window preventing the button events delivery (but motion events are still delivered via xinput2, which makes it all look very obscure)."

Fixed bug 2500 - X11: SDL tries (and fails) to hide foreign windows Alvin I'm interested in this bug as well. I have experienced it when trying to embed an SDL_Window into a FLTK application. To do this, I create a FLTK window (window inside a window - think video player) and then use SDL_CreateWindowFrom() on the inner most window's Xlib Window*. After which, I create a renderer. In my situation I am using the FLTK GUI toolkit. What I have experienced is that the SDL_CreateRender() will recreate the window in order to properly setup OpenGL capability. As part of this process, the window is hidden and a call is executed that waits indefinitely for an acknowledgement that the window was indeed unmapped. This is where my program hangs. Please correct me if I am wrong, but should SDL2 not make Xlib calls that effect the Xlib Window in this situation (e.g. When SDL_CreateWindowFrom() is used)? The toolkit being used typically assumes responsibility and, I presume, tracks all Xlib Windows it creates. On line src/video/SDL_video.c:1372 the comment associated with setting SDL_WINDOW_FOREIGN reads: /* Can't destroy and re-create foreign windows, hrm */ Since I do not know the reason for hiding the window in the first place, the attached patch simply does not wait for a response when X11_XWithdrawWindow() and X11_XMapRaised() are issued by X11_HideWindow() and X11_ShowWindow(), respectively. I presume that the GUI toolkit (GTK, FLTK, etc.) has or will consume the acknowledging event as it is managing the Xlib Window (or it thinks it is). I have tested the patch against hg 5c645d037de2 and I have successfully tested: * Embedding the SDL_Window inside a FLTK application. * Calling SDL_SetWindowSize() when FLTK resizes the window (e.g. dragging cursor on the edge of the window). * Filling the renderer's default target blue and drawing a red fill square at the centre (exciting, I know!) * Calling SDL_Quit() when the application terminates I do not receive any Xlib erorr messages (BadWindow, etc.) in any of those situations.

Fixed bug 3410 - SDL_WINDOW_HIDDEN flag is inaccurate. Jason Wyatt After hiding the window, SDL_WINDOW_HIDDEN/SDL_WINDOW_SHOWN flags on a window are correctly updated. However on the next SDL_PumpEvents, they are set incorrectly. This appears to be because X11_GetNetWMState does not check whether the _NET_WM_STATE property exists (it shouldn't on unmapped windows, see https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html#idm140130317598336). This results in an empty list of atoms for the state, which would imply that the window is not hidden. (Seen on Fedora 24, Gnome) -- Dan Ginsburg More details on my proposed patch: I am on Kubuntu 16.04.2. I ran into this same bug, but with Jason's patch I found that actualType != None was true so the SDL_WINDOW_HIDDEN would still not be set. My fix instead is to explicitly check for whether the window is unmapped rather than relying on the returned values in XGetWindowProperty.

(For bug #2570) - Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum OpenGL ES version supported by the OpenGL driver (for bug #3145) - Modifies the test that determines whether to use the OpenGL driver or the real OpenGL ES driver to take into account the hint, the requested and supported ES version and whether ES 1.X is being requested. (For bug #2570 & bug #3145) - Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds the test to the VisualC projects. With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.

SDL_SetWindowTitle() should never set a NULL pointer for the title string. Various backends reacted differently (or not at all) in the presence of a NULL pointer. This simplifies things. Fixes Bugzilla #2902.

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!

[X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam

Fixed bug 2629 - Mac: crash when calling SDL_DestroyWindow with an active OpenGL context Alex Szpakowski Since this commit https://hg.libsdl.org/SDL/rev/59b543340d63 , calling SDL_DestroyWindow will crash the program if the window has an active OpenGL context. This is because the Cocoa_DestroyWindow code sets the window's driverdata to NULL and then calls [context setWindow:NULL], which tries to access the window's driverdata, resulting in a null pointer dereference. I have attached a patch which fixes the issue by moving the line which sets the driverdata to NULL to after the lines which call functions that use the driverdata pointer.

Changed drag area API to a hit-testing API. There were several good arguments for this: it's how Windows works with WM_NCHITTEST, SDL doesn't need to manage a list of rects, it allows more control over the regions (how do you use rects to cleanly surround a circular button?), the callback can be more optimized than a iterating a list of rects, and you don't have to send an updated list of rects whenever the window resizes or layout changes.

Fixed bug 2101 - CWBackPixel causes weird window flickering on window resize aBothe I tried to experiment a bit with SDL2 and OpenGL today and noticed that something caused some weird flickering when resizing my nicely drawn SDL2/OpenGL window: Just after resizing, the background went black and I had to let my OpenGL code redraw the contents.. However, after some hours spent with googling I found out that in OpenGL examples where this CWBackPixel flag was not used when creating X windows, there was no flickering while resizing the window. See http://www.sbin.org/doc/Xlib/chapt_04.html @ "The Window Background" for more info.

Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
