** Attachment added: "video showing flicker and dark band"
   https://bugs.launchpad.net/bugs/965557/+attachment/2942710/+files/VID_20120326_104435.mp4

** Description changed:

  When logging into an "Ubuntu" (compiz/unity) session, I get heavy
  flickering whenever new windows are created or when windows are moved on
  screen.  I also get a dark band that gradually appears under the top
  panel and gradually obscures any content under it.
  
  The attached video shows these symptoms.
  
  This is all on a Thinkpad X60.
  
  These symptoms are not present - everything seems to display properly -
  when logging into a "Ubuntu 2D" (metacity/unity) session.
  
+ This problem appeared after an aptitude full-upgrade on 2012-03-23 and
+ has persisted until now.  This machine has been running compiz/unity
+ sessions without problems since Natty.
