@ tkoun & UbuntuTeam : I don't think Ubuntu can revert compiz to 0.8.6 version in Natty. This would break Unity that is the real new stuff in Natty. And, I think the bug is more trivial than we think, the difficult is to find it in the code.
But, definitively, it is related to compiz.
@ tkoun : thank you for the feedback.
