I can confirm this problem with compiz 0.9.7.12 and nvidia 334.21 on Ubuntu 12.04 64bit. It seems compiz doesn't handle damage events properly with this driver - parts of windows are not updated when they should be, leaving them rendered in an inconsistent state. Seems to affect any gtk application.
