I think it's not connected to specific ATI drivers. I have the same fail on two different machines: 1) notebook with Core 2 Duo and NVIDIA GeForce 8660 2) desktop with i7 3770 (with embedded Intel HD 4000). Fail is often caused by firefox, but may happen at any other time. Also, bug disappeared after switching to unity-2d. My `lspci` on the second computer:
