Screen flickers at random times with nvidia 270.30

Binary package hint: xorg

Random screen flickering with nvidia beta 270.30.

I am not sure if its an upstream nvidia bug or xorg related.

-flickering is happening at random times, maybe only with external screen attached

-mouse moves, but clicks are not recognized
-xserver/driver seems to recover after some time (~1minute)
