[Daniel van Vugt <vanvugt@xxxxxxxxx>]

OK, it turns out the desktop tearing fix in bug 880707 is not enough to
also fix this bug. This one seems to mostly be about tearing when
playing video (usually HD) if I'm not mistaken.


** Summary changed:

- [sandybridge] video tearing
+ [sandybridge] Graphics tearing when playing video

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  Videos tear heavily.
  
- WORKAROUND: See comment #28
+ WORKAROUND:
  
+ Enable "Force full screen redraws (buffer swap) on repaint" in the
+ Workarounds section of ccsm. If you don't have ccsm installed, you can
+ get it by installing package "compizconfig-settings-manager".
