Same problem with Ubuntu 14.04.1, Chrome Version 39.0.2171.65 (64-bit) I think this issue is related to the driver of video card. I am using Nvidia GForce 8400 GS.

The problem only manifests itself in compiz and Xorg when it appears in Chrome, so one would suspect it's something Chrome is doing, but maybe compiz could be more resilient. If it is a Chrome problem, it would be nice if I could squeeze some debugging out of compiz to prove this. Unfortunately, it appears to be non-deterministic, so I can't provide any steps to reproduce.
