GPU crash dump

It's an Acer C720 Chromebook running Arch Linux x86_64.

dmesg's last lines:
[ 5168.242205] perf samples too long (2507 > 2500), lowering
kernel.perf_event_max_sample_rate to 50100
[13802.523971] perf samples too long (5000 > 4990), lowering
kernel.perf_event_max_sample_rate to 25200
[13924.032406] [drm] stuck on render ring
[13924.032425] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[13924.032430] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[13924.032434] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[13924.032438] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[13924.032442] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
