Title:
  [HP Workstation z420, Z820]: Unity menu dock visually corrupted after
  resume from suspend.

Status in “nvidia-graphics-drivers” package in Ubuntu:
  New

Bug description:
  Problem encountered:

  I've seen this happen on a couple of machines running 12.04 LTS with
  base 3.2.0.23 kernel level.

  1.) Choose suspend from menu drop down.
  2.) Shake mouse or hit key to resume
  3.) System will resume and unity launcher on the left hand side will be 
distorted. Display is otherwise fine.

  Workaround:

  All you need to do usually to clear the distortion is to hover the
  mouse icon over the  affected launcher menu. The menu will then return
  to its original unaltered condition.

  Reproducable? Yes, this can be reproduced after every suspend in a 250
  cycle loop.

  Screenshot is attached.
