Thanks for your response.
But like I told, Tiling Assistant is not installed on this system, so I cannot
test the suggested workaround.
For reference, gnome-extensions info [email protected] reports that
the extension does not exist, and the corresponding Ubuntu package is not
installed.
I also want to point out one difference from bug #2117277: my preserved core
shows an X11 path
meta_window_x11_client_message()
-> meta_window_unmaximize()
-> meta_window_get_work_area_current_monitor()
-> meta_window_get_work_area_for_logical_monitor()
with window->monitor == NULL.
Bug #2117277 appears to have been fixed upstream via MR !4549 in core/place,
whereas this crash does not pass through meta_window_place(). So although both
failures have the same NULL logical-monitor assertion and may share the same
underlying monitor-hotplug state, I am not sure whether the existing fix for
#2117277 also covers this X11/unmaximize path.
I still have the original core dump and matching debug symbols if any further
inspection is useful.
