Bug Description
The computer running Ubuntu is being used as HTPC connected via HDMI to a screen projector.
After upgrading to 16.04, it's unusable under production kernel.
The screen starts flickering after a while (it's easily triggered by fast scrolling e.g. terminal's window). The whole screen get's filled with a noise, and then the projector gets disconnected for a while.
The computer runs fine on an older kernel (4.2.0-35), it's still broken on the mainline kernel 4.7.0.
