[Bug 782810] [NEW] xorg and compiz hog the cpu

 

Public bug reported:

Binary package hint: compiz

Description:	Ubuntu 11.04
Release:	11.04

The computer has become a lot slower since upgrading to Natty. When
observing top, xorg and compiz often are at the top of the list taking
up 10% to 40% of the CPU each. This doesn't happen all the time but it
does happen often. I don't think that it's the fault of any program that
I run because it is sometimes like this right after a reboot.

I am using the Ubuntu Classic session as the Unity session is almost
unusable because it is so sluggish.
