[braikar <braikar@xxxxxxxxx>]

I have the same flicker problem, (linux mint 17 + mate 64bits, so based
on ubuntu 14.04) with a gtx750ti 340.32 driver with compiz Compiz
0.9.11.2 from the ubuntu 14.04 standard packages but I didn't install
any patch.

For me what seems to do the trick, was enabling:
Utility > Workarounds > Fix screen ypdates in XGL with fglrx
& Utility > Workarounds > Force synchronization between X and GLX (which is said to be good for nvidia cards!)

I installed the patch and I see it adds a General > OpenGL > X11 Sync
objects! So I was on the right track it seems ;) Anyway, thank you very
much for the PPA, the patch seems to fix the flickering for good.

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. "
