Comment 19 for bug 980663

Sorry forgive me after the latest updates, I can now enable 'unredirect fullscreen windows' and reboot into Unity fine.

So this issue seems solved ? (anyone else seeing this?)

However the issue remains that by default, for Nvidia + Unity users performance is terrible, but not just that it has rendering issues also - its a compiz rather than unity issue btw:

so 'out the box' a Nvidia user's experience in Unity is going to not be good....

Just clicking that option makes such a world of difference in performance
