Title:
  Intermittent screen flicker on Dell XPS 13 (9350)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to Ubuntu 16.04, I have been noticing intermittent
  screen flickers where the screen blacks out 2-3 times every couple of
  minutes for about a quarter of a second or so. This is running the
  stock kernel that came with the release (4.4.0-21).
