Here is the crash dump attached as requested. dmesg says:


[ 2578.757192] [drm] stuck on render ring
[ 2578.757703] [drm] GPU HANG: ecode 7:0:0x00000000, in kwin_x11 [1560],
reason: Ring hung, action: reset
[ 2578.757704] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2578.757705] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2578.757705] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2578.757706] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
