Bug description:
  [Description]
  When hovering over icons on unity or using an application which does a lot of re-drawing there is significant flickering and graphic corruption. This only happens in 12.10 downgrading to 12.04 fixes the issue. 

  [Work Around]
  unity --replace sometimes fixes the issue (ie you have to do it two or three times, but eventually it does fix it and the issues doesn't re-appear for that desktop session). 

  [Easiest way to force the flicker]
  I have found the easiest way to force a flicker is to drag a window frame to the right hand side of the screen so the yellow bounding box appears on the right half of the screen, when this happens a lot of flickering occurs. 

  [Possibly duplicates]
  I've found a few bugs with similar problems, however these are for different versions so wasn't sure if they were duplicates or not bug #963093 ; bug #1059467
