Bug Description

This could very well be a problem further down in kms or elsewhere in the graphics stack.
I recently updated from vivid to wily.
I had a very reliable setup of being able to connect an external monitor to my macbook display port for an "extended" dektop view (not clone). This now flickers in quadrants, and the flickering quadrants on the monitor
video shows it best
