Title:
  Strange flashing application switcher

Status in Unity:
  Confirmed
Status in Unity 7.2 series:
  Confirmed
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  I will attach a video that shows the issue.
  The app switcher (ALT+Tab / ALT+^) flashes while I don't switch between windows (it seems to be a dark shadow that is getting darker, goes away and reappears right away).
  I found out that this only happens when I have Chromium OR Spotify open (and not minimized, they don't need to be in front however). There might be other apps which are causing the same issue.
