I was still having this bug on a fresh install of 14.04 (kernel 3.13.0-24-generic). Strangely, since setting i915.semaphores=1 (suggested at http://askubuntu.com/questions/50033/unity-gui-pauses- freezes-for-less-than-a-few-seconds/ all the way back in 2011) I no longer get hangs. The default value of i915.semaphores seems to be -1 (according to `cat /sys/module/i915/parameters/semaphores`) and the advice elsewhere of setting i915.semaphores=0 had no effect for me. Hardware: i3-2120 (Sandy Bridge HD 2000 graphics) + Asus P8H61-M PRO motherboard.
