Description Jonas Thiem 2011-06-20 08:35:36 UTC 
When creating a fullscreen window and using a SDL_CreateRenderer() with SDL_RENDERER_SOFTWARE flag on it, the Linux Gnome 3 desktop environment doesn't properly fullscreen the window despite successful resolution change (window title bar and the desktop's top status bar stay visible, part of the window contents are not accessible). When picking a normal accelerated renderer with SDL_RENDERER_ACCELERATED (opengl), it works perfectly.

This makes using a fallback software renderer for users with problematic video drivers (not rare on linux) not feasible for fullscreen games which is a bit odd.

This seems to be the output that identifies the current hg revision I use (sorry if it is not, I am not familiar with hg):

I got a workaround:

Starting windowed and then after 5 seconds running SDL_SetWindowFullscreen(mainwindow, SDL_TRUE);
gets me a properly working fullscreen mode.

If I use SDL_SetWindowFullscreen(mainwindow, SDL_TRUE); right after SDL_CreateWindow()/SDL_CreateRenderer(), I get just the broken fullscreen though (so the same bugged behaviour as with  direct fullscreen as described in this bug report).

The problem is seemingly resolved, probably due to a bugfix in gnome 3 itself.

Great, thanks for the update!
