Comment 130 for bug 1288747

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.
