Bug#602207: xserver-xorg-video-intel: Swiching SDL window to fullscreen causes black screen

[Christian Henz]

I'm also experiencing this problem, ever since the last round of Xorg updates 
(on 23rd of october according to my dpkg.log).

I wrote a small test program that exposes this behaviour. One thing 
to note is that the problem only occurs if the program in question is
running at the native screen resolution (1680x1050 in my case).

So for example 
  1024x768/fullscreen -> 1024x768/window -> 1024x768/fullscreen
works here, but 
  1680x1050/fullscreen -> 1680x1050/window -> 1680x1050/fullscreen
does not.

cheers,
Christian

  SDL_Delay( 3000 );

  SDL_WM_ToggleFullScreen( screen );
  SDL_Delay( 3000 );

  SDL_WM_ToggleFullScreen( screen );
  SDL_Delay( 3000 );
