Fixed bug 4000 - SDL2 on raspberry: mouse displayed at 0,0 after SDL_ShowCursor Laurent Merckx I have a problem with the SDL_ShowCursor method on Raspberry. Depending on the context, my application hides or show the mouse cursor with SDL_ShowCursor. But when calling SDL_ShowCursor(true), the cursor is displayed at 0,0 (and not at last position). After debugging sources by myself, it seems that the problem is in SDL_rpimouse.c - RPI_ShowCursor: vc_dispmanx_rect_set( &dst_rect, 0, 0, curdata->w, curdata->h); should be vc_dispmanx_rect_set( &dst_rect, mouse->x, mouse->y, curdata->w, curdata->h); For me, it solves the problem.
