** Description changed:

+ [Impact]
+ 
+ Tearing on some drivers in some video applications.
+ 
+ [Test Case]
+ 
+ Use intel graphics and run http://www.youtube.com/watch?v=ZCPkOpMHB7g in
+ full screen mode.
+ 
+ [Regression Potential]
+ 
+ None, restores current behavior for the specific applications as a
+ driver/application workaround.

  Using "Unredirect Fullscreen Windows" can cause significant tearing in
  the fullscreen window being unredirected.
  
  This is an unavoidable consequence of "Unredirect Fullscreen Windows".
  Removing compiz from the equation and allowing windows to render
  directly to the screen means compiz has no control over the window and
  cannot prevent tearing any more.
  
  Workaround (1):
  CCSM > Composite > Unredirect Fullscreen Windows = OFF
  -or-
  Workaround (2):
  Check the settings of the application running fullscreen. It should have an option called something like "sync to vblank" which you can enable. If not, use a different app.
