Description of problem: SDL_WM_ToggleFullScreen does something wrong to the image: the screen splits in two parts and the lower part shakes, also on a LCD screen. This breaks all SDL-based games, too. full screen xscreensave hacks are ok (tested with /usr/X11R6/lib/xscreensaver/antspotlight -fps -delay 0 -root). I saw this problem first on fc2 but could reproduce with rawhide version as well. Version-Release number of selected component (if applicable): SDL-1.2.7-3 and SDL-1.2.7-7 How reproducible: Always Steps to Reproduce: 1. Compile attached test program with cc fullscreen.c `sdl-config --libs --cflags` 3. run it and move the move the mouse pointer up and down - you will see the pointer screen wide when crossing the middle of the screen, Actual Results: You will see the pointer screen wide when crossing the middle of the screen. Expected Results: Smooth black image. Additional info: LIBGL_ALWAYS_INDIRECT=y does not remove the problem.
Created attachment 103001 [details] fullscreen.c The test program - but running any full screen SDL-based program will most likely do.
This is a driver problem, not a SDL problem. Assigning to X.
