Bug description:
  There's a call to damageScreen in UnityScreen::nuxDamageCompiz that I
  had to put there to work around rendering bugs when we did the GLES
  port. It has a significant impact on performance however and should be
  removed ASAP, replaced with something like the old version of
  UnityScreen::nuxDamageCompiz.

  I think this is causing bug 1039942, and probably others too.
