Being an upstream maintainer of Compiz, I would absolutely love to
accept the patch.  However, somehow Compiz falls under the CLA and we
are still trying to get Nvidia (who provided the patch) to agree to it.
Trust me when I say there have been ongoing discussions to get this in.
We are dealing with glacial process of legalities *sigh*

Title:
  [334] Parts of the UI randomly flicker when moving the mouse

Status in Compiz:
  Triaged
Status in compiz package in Ubuntu:
  Triaged

Bug description:
  Nvidia 334.21 makes the UI jearky, googled and found this on Nvidia
  forums:

  "This looks like a problem caused by the system compositor not
  properly waiting for X rendering to finish before performing OpenGL
  rendering in response. The GL_EXT_x11_sync_object extension was
  designed to solve this problem, but it looks like cogl (the back-end
  library used by GNOME's compositor) doesn't use it yet. "
