*** This bug is a duplicate of bug 1505409 ***

JournalErrors.txt is showing that Xwayland crashed, which is a fatal
error for gnome-shell and it gives up. So that would make this a
duplicate of bug 1505409 or bug 1556601.
However the same log shows other shell crashes too:
Sep 15 16:28:21 hostname gnome-shell[1393]:
meta_renderer_native_release_onscreen: assertion
'onscreen_native->gbm.next_fb_id == 0' failed
Sep 15 16:28:21 hostname gnome-shell[1393]: _cogl_onscreen_free: assertion
'onscreen->winsys == ((void *)0)' failed
and
Sep 15 17:38:43 hostname gnome-shell[10327]: clutter_actor_is_visible:
assertion 'CLUTTER_IS_ACTOR (self)' failed
Sep 15 17:39:02 hostname gnome-shell[10327]: remove_mnemonics: assertion 'label
!= NULL' failed
and
Sep 18 08:05:58 hostname gnome-shell[10327]: clutter_actor_lower: Actor of type
ClutterActor is not inside a container
Sep 18 08:05:58 hostname gnome-shell[10327]: _cogl_pipeline_override_uniform:
assertion 'cogl_is_pipeline (pipeline)' failed
So you're getting a bunch of different crashes that each need their own
bug reports. I suggest we close this bug because it's become conflated,
and then pursue each crash with separate bug reports. Either wait till
you can get a .crash file or stack trace, or wait till one of those
assertions reoccurs and log a new bug about that.
