Do you know if this problem can have anything to do with my card being overheated or simply faulty? I read somewhere that overheating cards can produce similar Xid lines.
Is there anything else I can do to further diagnose the problem? I would very much like to know what those Xid lines mean.
Finally it appears that this problem is not limited to OpenGL applications. When I leave X running it occasionaly locks up in a similar manner, only far less often. As you can see I'm quite desperate to find a solution
