--- Comment #11 from jost mail@jost.cx 2011-01-25 02:00:12 CST --- Well, i don't thik you are completely right. I use Catalyst 9.3, because there is no newer version available for my graphics card (Radeon x850)
So i can't go back from 10.12 to 10.10 ;-)
But i agree that the Ati Catalyst driver might be the problem. I will try an open source driver as soon as i reinstall my system. http://www.x.org/wiki/RadeonFeature
