Public bug reported:

I am using the Dell XPS 13 9350 with Ubuntu 16.04, and I am experiencing
random screen flickering where the screen will flicker to black for a
split second.  This happens repeatedly every few seconds for half a
minute or so.  Then the issue will disappear for a few minutes, but
randomly come back.

I have experienced using Ubuntu 16.04 with Unity, Gnome, and XFCE.  I am
running the latest BIOS version 1.3.3.
