Bug#878221: linux-image-4.9.0-4-amd64: Screen flickers randomly with Radeon R9 270X since upgrade from 4.9.0-3 to 4.9.0-4

[Paul Boekholt]

I spoke too soon, after a while my eDP-1 starts shaking when I move my mouse. 
It's also shifted, or should I say rotated. The external monitor is fine now 
though.
