Bug Description
Update: I posted in bug #153204 for Compiz (Ubuntu). Confirmed that Compiz deactivated fixes the problem. That doesn't mean the problem isn't there...
Using:
Intel C2D 2180
ATI HD 3870
2GB Corsair RAM
WD 320GB
Ubuntu 8.04 64-bit (Alternate Install CD) (Installed to disk AND using Wubi)
Closed source ATI drivers
Description:
When playing a game full screen (I've tried Nexuiz and Unreal Tournament 2004) in GNOME, the screen "flickers", rather, part of the screen goes black for an instant every second or two. This does not happen in Openbox or XFCE (as installed from default Ubuntu, have not tested with Xubuntu). This leads me to believe that it is a problem between fullscreen games (the ATI driver?) and some package used only in GNOME.

"The problem lies in the compiz call to GL_pixmaps... that is not recognized and so compiz defaults to indirect rendering which uses a lot of cpu resources and causes a vastly reduced frame rate. This in turn causes ANY process that needs a rapid frame rate to flicker if compiz is running.

True. It's actually the popups. You know, the notification balloons? It's those.
