Fixed bug 4991 - Pixel shader problem when recreating a texture for direct3d renderer cmediaplayer Hi, i already mentioned in the SDL discourse a bug that recreating of a texture occours pixel shader problem on direct3d renderer. There is no problem for direct3d11. You can see the issue by using my app named C Media Player which is available for Windows for free using my web site www.cmediaplayer.com. Just follow the steps: *Open a media file *When playing the file change the scale quality under the video menu. *You will see the problem.
