http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu which installs version 2:2.7.1-0ubuntu1~xup~1 with Option "AccelMethod" "exa", Option "EXAOptimizeMigration" "true", Option "MigrationHeuristic" "greedy", and Option "Tiling" "true". I tried UXA too, but every 30-60 seconds my screen would glitch, so I switched to EXA (which doesn't it default to that). The delayed scrolling in Firefox is the main graphics issue I'm having and it is slightly worse with compiz. I use Flashblock, so it can't be that. The animations in compiz are fine though, no glitches, and very smooth. I don't have smooth scrolling enabled either. Any clues for us i945GME users?
