I'm not a fan of binary blobs, but ever since I've installed catalyst, I have had no problems with video tearing/ X crashes. I even use compiz and its quite nice (there is a slight discontinuity if you move the windows very fast though. Its a small point, but I would have liked it to be smoother). I have also had no problems with projectors/external monitors after using catalyst. (using radeon HD4300 which is probably an old card by now)
Gnome 3 shell on OpenSUSE 12.1 and Fedora 16 regularly (at least 10 times a day) crashes when using catalyst drivers on my HD5650. Using the opensource drivers it works fine. Chrome blacklists the GPU/drivers so no WebGL without --ignore-gpu-blacklist, WebGL performance is ~ old TNT2 in chrome/firefox (although that can be simply because WebGL implementation/app isn't good). I used to buy ATI/AMD because they offered good price/performance ratios but I'm going to go with nVidia/Intel for my next PC, it's going to have to suck really bad to provide a worse experience than this.
perhaps I should have clarified a bit.... I use Debian Squeeze which uses gnome2, and on it I have had no problems for the whole of 2011 (and I run advanced visualization softwares such as VTK on large datasets, still no trouble). Maybe the problem has to do with gnome3? (No problems with chrome/WebGL either.)
It certainly does - but it's also driver specific because on open source drivers it works without the crashing - but then the performance is terrible, even playing YouTube fullscreen lags (!?).
