Comment 2 for bug 1257382

Ok, I've tried apport-collect 1257382 and I get the the message "no additional information collected"
I'm running Ubuntu 14.04 64bit with Nvidia Gtx680 with 331.20 driver version.
Vsync is enabled in control panel and Compiz. Unredirect full screen windows is also enabled.

For example download this unity3d game demo http://ultrarunaway.itch.io/paper-sorcerer-demo and you'll notice that vsync is not working unless a non composited environment is used like openbox.
Unity3d games are detecting a compositor and disable vsync automatically, but that shouldn't happen with Unredirect full screen windows enabled.
