At first look, I thought that they solved the problem:
* I've used Compiz effects without problem
* I played OpenArena during 5 minutes (in medium configuration) without problem
BUT...
* When I've opened Blender, it froze instantly.
* When I was writing a message here about this behaviour, the system froze again (exactly when a Firefox's tooltip appeared).
If I remember correctly, the same used to happen in Jaunty. We know that the biggest problem is in version 7.6 of the Mesa. But version 7.5 also brings problems (though smaller).
I still think that the problem has something to do with transparency effects (mainly because of the problem of the tooltip).
In short, the problem persists. At least in my case.
Well, I've tried this set of packages.
