I noticed the game becoming unresponsive for a few seconds while playing; I saw
this in my kernel messages later:

[240918.898139] [drm] stuck on render ring
[240918.898845] [drm] GPU HANG: ecode 7:0:0x85dffff8, in lotroclient.exe
[13281], reason: Ring hung, action: reset
[240918.898846] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[240918.898846] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[240918.898847] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[240918.898847] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[240918.898847] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[240918.900045] drm/i915: Resetting chip after gpu hang

This is on an i5 4690k (HD graphics 4600) running with intel_iommu=on.

I'm not sure how reproducible this is.
