Comment 70 for bug 935630

Alright, thanks for all the feedback. Given that the boxes go away when logged out, and that Denver is on -radeon whereas Andreas is -intel, it is likely sounding not to be a driver issue. It is probably compiz doing something wrong.

I see there are similar bugs against compiz, #940603 and #753606, but the symptoms differ, so not setting as dupe. (940603 is also against chromium, so may be pertinent)
