  Text repaint problems in Emacs

Bug description:
  I experience text repaint issues in Emacs when running under Unity.

  The following video demonstrates the problem:
  http://www.youtube.com/watch?v=VWh4kEecVsQ

  Text glyphs vanish and reappear in strange ways. Checking option
  "Force full screen redraws (buffer swap) on repaint" in CCSM makes the
  problem go away (also shown in video).

  The problem does not occur when running Emacs under for instance
  Openbox. Might be related to compositing and/or nvidia. I experience
  the problem on two different computers (both Nvidia), although it's
  easier to reproduce on one of them.

  Ubuntu 12.04 x86-64
  Nvidia driver 304.64
  Unity 5.16.0+bzr2410sruubuntu0+709  (also happens with Unity 5.16.0-0ubuntu1 from precise-updates).
