        <pre>After upgrading to linux 3.14 rendering issues appear. This occurs most often
while using firefox, but also outside firefox.
Sometimes the screen freezes and after a few seconds KWin says it reset the
graphics and everything works again. This is the relevant dmesg output:

[  695.078683] [drm] stuck on render ring
[  695.078692] [drm] GPU crash dump saved to /sys/class/drm/card1/error
[  695.078695] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
sta
ck, including userspace.
[  695.078698] [drm] Please file a _new_ bug report on bugs.freedesktop.org
agai
nst DRI -> DRM/Intel
[  695.078700] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  695.078702] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I use arch linux with xorg-server 1.15.0-5. Linux 3.13.8 works fine.</pre>
