Although I appreciate your tests performed, they show nothing more than the workaround that has been around for quite some time, namely, disable compiz. You were saying that you believe it was something nvidia changed in their new drivers, I have to disagree with reference to J N B's and my own experimental findings where the same drivers worked in 8.10. It is thus more likely that this is caused by an x.org issue as the discussions between J N B and Travis indicates.
