Had this happen a few times now, where closing the main evolution window (last visible window on desktop) results in a gnome-shell crash (see bug 1821262)

I can't find any other reports of a crash like this.

On the slight chance these are related, please uninstall the extensions:

['audio-input-switcher@anduchs', 'audio-output-switcher@anduchs', '<email address hidden>', '<email address hidden>', 'audio-switcher@AndresCidoncha', 'output-audio-devices@muflone']

and then tell us if the problem persists.

[Joe Barnett (thejoe)]

problem persisting with extensions uninstalled & disabled:

$ gsettings get org.gnome.shell enabled-extensions
@as []

[Joe Barnett (thejoe)]

Anything else I can do to help debug this?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

Unless you can think of anything that's special or unusual about your system that triggers this bug?

It took a while, but we now are getting other reports of this same crash via:

Not sure if related, but I do run under wayland (weird that it looks like an X11 error then, especially as evolution runs wayland native?), with fractional zooming on my laptop panel @ 175% and usually have an external, lower resolution screen at 100% scaling. Evolution is usually the first app i open and stays open throughout my session, so has usually been running for days before being closed (and killing the session) -- but sometimes closing it is fine. Haven't seen any other app trigger it.

[Daniel van Vugt (vanvugt)]

When you see X11 code in the gnome-shell process of a Wayland session that's nothing unusual. It just means some X11 app is running, talking to Xwayland and gnome-shell (which is both the Wayland display server AND the X11 window manager in this case).

Since this bug is about a particular "BadWindow (invalid Window parameter)", maybe it is specific to Evolution?...

[Jean-Louis Dupond (dupondje)]

I have an 100% reliable way to reproduce this crash :)

Take a screenshot & copy to clipboard, try to paste the image (clipboard content) inside a telegram-desktop chat -> BOOM, gnome-shell crashes
