Public bug reported: Probable duplicate of: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/737454
I experienced this problem in earlier versions of Ubuntu primarily when my console windows were really large. If I made them smaller, the CPU usage would drop dramatically, to much more reasonable levels. That does not seem to be the case in my current version of Ubuntu (11.10). Compiz is taking up 80-90% of one CPU consistently, and resizing console windows only helps to an extent. I do not have transparency enabled. I do note a similarity with the bug linked above -- I have a dual-head setup.
