I used mint 16 and it was ok here in 17.1 I suffered a longtime from "video tearing" tried a lot of online solutions, even I updated the kernel and comes from nowhere I find that "marco" here is the cause of this big problem...changed to compiz and video tearing vanished right away.
Why do you need both Metacity and Marco? They both do the same thing and it’s questionable that either is needed. OK, so it is needed, but you couldn’t combine the two?
