PaperWM crashes GNOME

[mawkler]

Describe the bug

PaperWM randomly crashes GNOME shell. Below is the output of running this journalctl -b -1 --since "08:03:00" --until "08:04:16" | grep -i "gnome-shell\|mutter\|wayland\|segfault\|signal\|core dump" after my most recent crash.

Also notice that it reports 18 GB memory usage from GNOME shell, could that be a memory leak in PaperWM?: "Consumed 1h 28min 21.374s CPU time, 18.5G memory peak, 12.0G memory swap peak".

I am having the same issue. For me GNOME becomes completely unresponsive, with the cursor still movable.

[Thesola10]

@mawkler Do you use multiple monitors? This line seems to suggest a multi-monitor-related crash:

meta_monitor_manager_get_logical_monitor_from_number: assertion '(unsigned int) number < g_list_length (manager->logical_monitors)' failed

@Lucasej800 are you sure this is the same bug?

[mawkler]

@Thesola10 Yes I'm using multiple monitors

I see a similar log after unsuspending my laptop, plugging into dock, then unlocking:

However, GNOME does not crash, just hangs. In this case it recovered from the hang after about 15 minutes.

I see this when it recovers from the hang

When this happens to you guys, by pressing Super (to activate the overview of the open apps) and then Esc does it not solve the problem?
