[Stuart Gillies <1072206@xxxxxxxxxxxxxxxxxx>]

I have started to get this on my 14.04 double-header nvidia amd64
system.  I can't say what events cause it, but moving a window generally
fixes it until the next time.  I don't need to have a lot of windows
open to see it.

Bug description:
  Ubuntu 12.10 64bit (updated from 12.04) / NVIDIA GeForce 8 proprietary
  driver.

  This bug happens to me from 12.04 from some update I think.
  It appears mostly when I open a new application and only ocassionally.
  As temporary "solution" creating some other event like opening Unity dash or opening some next window, etc. fix it. Then window content is refreshed and I can see all correctly.
  Same with stable and experimental nvidia drivers.

  Screenshot of this bug is attached.
