Comment 7 for bug 175774

I also have this problem. I have also had seemingly random Compiz crashes (using 100% CPU and necessitating a kill -9 via ssh). I'm still trying to figure out where the problem is, but given the severity of the crash, I suspect it is related to this. When I was running Gutsy, I used XAA and made sure my video apps didn't use Xv, and I did not have such problems.
