          Hardware: x86-64 (AMD64)

Short video which shows the screen flashing. Ignore the visible (light)
background near top in the video, it's an artefact produced while recording.

Some backstory:
Lubuntu 16.04 didn't have `xserver-xorg-video-intel` installed by default,
which caused some problems (https://bugs.freedesktop.org/show_bug.cgi?id=96795)
but other than that playing 3D games and HD videos worked perfectly, so I
installed that package and reinstalled other graphics components from Ubuntu's
repository. This made the aforementioned bug go away, but created an issue
where the screen flashes/flickers while playing games, while it is stable every
other time.

See attachment to see the flashing. (Recorded with SimpleScreenRecorder) 

xserver-xorg-video-intel, version: 2:2.99.917+git20160325-1ubuntu1
Kernel: 4.4.0-28-generic
Distribution: Lubuntu 16.04 fresh install
