Bug#415227: Bug#433167: compiz: fullscreen opengl games end up showing only a black screen

["Michael Gilbert" <michael.s.gilbert@gmail.com>]

i just tested with compiz 0.5.  enabling unredirect_fullscreen_windows
does make the screensaver work correctly (although it runs very
slowly).

also when using unredirect_fullscreen_windows, fullscreen opengl games
will run (after a black screen is shown for about 2 minutes) but they
will be very slow.  and now windowed opengl games also run very very
slow.

note that without using unredirect_fullscreen_windows, windowed opengl
games run fine and fullscreen opengl games result in a black screen.
