For those like me that did not want to use compiz on you nvidia machine because of the problems like windows screens not updating until you click or moved them, should be happy now. I know I sure am rotfl!
I can finally go back to compiz again after spending months in Kwin untill nvidia cared to look at the problem faced by so many users.
I know may be a little late (or alot late ) to be saying this, but for those who forgot to check the new 185.18.14 nvidia drivers seemed to do the trick.
