I've seen something like this on two machines with Intel and Nvidia
cards, respectively.

Fortunately I don't run compiz, but I found that after switching to
console and back, no OpenGL application would start anymore.
E.g. glxgears or prboom (with OpenGL renderer enabled) just hang right
at the start.  Restarting X is necessary to get OpenGL back.

I've downgraded to 2:1.7.7-4 now and the problem is gone.
