I confirm that I can see this bug also when using Catalyst (fglrx) drivers (both the version available in Oneiric and later versions avaiable from AMD's website).
In my case the issue is exacerbated by the number of active X clients. Closing some windows slightly improves the situation. However, I noticed this behavior in addition to performance degradation over time. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/888039 Title: Gradual degradation in desktop performance.
