Bug description:
  [ Impact ]

  When switching focus from one window to another, the target window may
  become blank. See the attached screenshot, where I opened two gnome-
  terminals and clicked on their titlebars alternately - the issue was
  triggered after about 5-10 clicks. I've had this happen on other
  appications too, e.g. software-centre, empathy, etc.


  [ Test Case ]

  Verification requires an nVidia GPU with proprietary drivers.  The
  problem can not reliably be reproduced at will, only after some time
  (depending on resident GPU memory and usage) and even then only

  1. Minimize a window
  2. Initiate Scale and deactivate it again (press Super+W to show all windows and then press it again to go back to normal)
  3. Click the window icon on the launcher to maximize it again.
  4. The window contents will be white, black, or transparent depending on the Ubuntu version

  [ Regression Potential ]

  It is unlikely this change has the potential to introduce new

  [ Other Info ]

  Fix was cherry-picked from the Ubuntu "Vivid Vervet" dev relase where
  it has been in use for some weeks without problem.
