I am on latest Hardy and I can confirm that bug is GONE! :-) I am sure that it was related to proprietary ATI driver. This is a history about my experience:

1) Enabling compiz was freezing my computer. Neither mouse nor keyboard does not work. Only remote connection or Reset button working. :-( It was on free (NOT-proprietary) Radeon driver, because when I use proprietary driver all the thing start running slowly. And I didn't khow why. But now I think I khow.
2) When Compiz was updated and its requirements were using only proprietary driver I got White Screen of Death.
3) And the happy end. Proprietary driver was updated and now everything is fine.

This is my opinion: when I click on "Use proprietary driver" system use WESA instead. This is why everything was so slow. And using free driver takes me to PC freezing. And when they fixed proprietary driver it solved the problem. Big thanks for developers!

I am using Radeon x550 plus.
