Xorg seems to crash randomly.  In dmesg, I see:
[26286.989369] [drm] stuck on render ring
[26286.991670] [drm] GPU HANG: ecode 7:0:0x85d77c1b, in Xorg [23231], reason:
Ring hung, action: reset
[26286.991675] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[26286.991677] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[26286.991679] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[26286.991680] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
