There seems to be 2 different issues here. bug 224893 (this bug) seems to be referring to fullscreen OpenGL application flickering with ATI cards bug 153204 seems to be referring to fullscreen application flickering (not necessary OpenGL apps nor ATI cards.) Workaround for this bug has been described in 3 posts above.
markbuntu in http://ubuntuforums.org/showpost.php?p=4990372&postcount=27 mentioned that "The problem is between compiz and the ATI driver. It has to do with a 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. One solution is to switch to metacity when using Google Earth or any other ap that flickers in compiz." I am marking this as confirmed as I believe that there is enough information both here and in the forum lined above. ** Changed in: compiz (Ubuntu) Status: Incomplete => Confirmed ** Summary changed: - Fullscreen games flicker in Ubuntu (GNOME only) + Fullscreen OpenGL games flicker in Ubuntu (GNOME only) ** Description changed: 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. + + markbuntu in http://ubuntuforums.org/showpost.php?p=4990372&postcount=27 mentioned that + "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.
