apport information

** Tags added: apport-collected precise ubuntu

** Description changed:

  Enabling alpha blur via ccsm causes various issues including making all
  windows invisible.  This happens when I use the gaussian blur method.
  4xbilinear and mipmap don't cause windows to be invisible, but they do
  cause various screen artifacts, and instead of alpha blur they result in
  the area behind being flipped horizontally (and not blurred).
  
  I am using Intel graphics (sandy bridge).  Please let me know if I can
  provide any more info.
