Comment 169 for bug 803943

I just updated three computers from Ubuntu 11.10 to 12.04. All have different ATI cards with drivers installed, and all have high cpu consuming by compiz. Though I haven't noticed any visible problems on the one of that computers. It's 4-cored notebook where interface responsibility isn't touched by this problem. Other two are 2-cored PCs and have noticeable interface lags compared to Ubuntu 11.10, making they almost unusable.
