Hm. Heaven hang dmesg output for the attached error state mentions Weston:
----------------------------------------------------
[  926.608756] i915 0000:00:02.0: GPU HANG: ecode 9:1:0xfffffffe, in  [0], hang
on rcs0
[  926.608757] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  926.608758] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  926.608758] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  926.608759] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

----------------------------------------------------

Maybe this slightly earlier Heaven hang is related to bug 110131 which I just
filed?

(Bug 110131 hangs started after switching from Ubuntu 18.04 desktop with Git
built Xserver to Git built libwayland/Weston/XWayland.)
