Can confirm this issue.  For example, if I keep "unredirected fullscreen
windows" turned on, and play Netflix in Google Chrome, for the most part
the movies do play without tearing, but as soon as I hit the volume
button and the OSD fades away, tearing happens and doesn't go away
unless the OSD is up.

But, turning off "unredirected fullscreen windows" fixes the issue.
Also switched to play the new Unreal Tournament engine, and saw no
performance issue by turning this off, so I am going to personally just
leave it off.

Title:
  'unredirect fullscreen windows' causes tearing

Status in compiz package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu release: 14.04
  Installed compiz version: 1:0.9.11+14.04.20140409-0ubuntu1

  The option 'unredirect fullscreen windows', which is enabled by
  default in Compiz, causes tearing in games and other fullscreen OpenGL
  applications, even with 'sync to vblank' options enabled in ccsm, in
  the GPU settings and in the game.

  With this option disabled, VSync works as fine as should with
  'unredirected fullscreen windows' enabled and there is no tearing (but
  this causes performance issues and the Unity panel shadow on top of
  the application).

  Tested with:
  - ASUS NVIDIA GTX 650-E-1GD5 with NVIDIA proprietary driver 331.38 (tested) (nvidia-331)
  - the same graphics card with NVIDIA proprietary driver 331.38 (nvidia-331-updates)
  - the same graphics card with Nouveau open source driver (xserver-xorg-video-nouveau)
  - Intel HD 4000 iGPU with default open source drivers

  
  *** NOTE TO PEOPLE REPORTING "SIMILAR" BUGS ***

  This bug is about unredirected fullscreen windows.  If you see menu
  bars, the Unity Panel, Indicators, a menu bar, a window title, or any
  other decorations you are not running in unredirected fullscreen mode
  and you are not experiencing this bug.

  A fullscreen window has content that occupies the entire screen, no
  borders, no menu bars, no Unity elements.  An unredirected window is a
  situation in which the application renders directly to the screen,
  without going through a compositor (such as Compiz).

  If you are seeing anything at all except your application content on
  the screen, this bug does not apply to you.
