changed with mouse movement for a little bit, until it then completely froze).

[11385.804027] [drm] stuck on render ring
[11385.804034] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[11385.804036] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[11385.804037] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[11385.804038] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[11385.804040] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
