X hangs reproducibly when changing a Xterm window with remote SSH login to a
screen window running rtorrent. After hanging cursor moves but nothing else
works and after maybe 30s X session dies and returns to login screen.

Hardware: Lenove T460s laptop with:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)

WM is awesome, OS Debian unstable running kernel 4.15.0-rc8-amd64 (also happens
with 4.14.13) and Mesa 17.3.2. Kernel log shows:

[   44.810470] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [802], reason:
Hang on rcs0, action: reset
[   44.810472] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   44.810472] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   44.810473] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   44.810473] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
