Bug Description
libsdl 1.2.11 added a bug fix for Composite extensions on XGL/AIGLX.
Unfortunately Ubuntu stable doesn't have this bugfix, and so applications that use SDL to draw to the screen will appear translucent.
This affects any application that directly uses SDL to draw to the screen, and that includes the popular PyGame framework (which is how I found it).
The easiest fix is to update libSDL1.2 to the newest point release. Otherwise backporting the fix will be necessary as Ubuntu moves to providing more Compositing extensions

This seems to affect games like Tremulous who become too dark to play effectively. http://
A temp solution could be to run xgamma -gamma 2 in the terminal before running a game.
