crash dump

It happens randomly (have to switch a few times), and the display freezes as it
is.  Switching to another TTY (which takes a few seconds) and back causes
everything to start working again.

CPU: i7 4770
System: Arch Linux, x86_64
Window manager: Compiz
Package versions:

linux 3.13.6-1
intel-dri 10.1.0-4
xf86-video-intel 2.99.910-1
compiz-core 0.8.9-3
vlc 2.1.4-1

dmesg output:

[  251.091143] [drm] stuck on render ring
[  251.091145] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[  251.091145] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  251.091145] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  251.091146] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  251.091146] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

Crash dump attached.
