activitity overview + screen lock crashed gnome shell (fedora 40, fedora 41) when dash to dock extension is enabled

[kk0nrad]

It's a very strange behaviour that I noticed when on fedora 40 and that still persists with fedora 41: I usually lock the screen with windows key + L, and sometimes it happens that I press windows key then windows key + L by mistake. When this happens, gnome shell crashes. I was able to track down the correlation with dash to dock because when the extension is disabled this does not happen at all.

I am experiencing the same. I checked the gnome shell logs, and I found the following:

Nov 30 21:15:12 fedora gnome-shell[10580]: Connection to xwayland lost
Nov 30 21:15:12 fedora gnome-shell[10580]: Xwayland terminated, exiting since it was mandatory

Does this only happen on Fedora?

I think that this was a bug in Gnome Shell itself... At least, I think that this same bug was commented here some months ago.

Yeah, this was the PR that I did as a workaround... in the comments it is explained the bug itself and the fix in gnome shell #2219

how can the fix be implemented? is there something I can modify on the fly? If the issue still manifests itself it means that the main bug hasn't been fixed yet, so I guess we sill need the modified behaviour for leaving overview mode before locking the screen.

I tried on Debian 12, which comes with gnome-shell version 43.9, and I could not reproduce the issue. The issue also never happened on Fedora 38 (which comes with gnome-shell 44). For me, I only started to notice the issue on Fedora 40 (gnome-shell version 46.6). To conclude, the issue may be present on gnome-shell versions > 44.

I found a related issue: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/7339

This one is relevant as well: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4851

As mentioned in the last issue, an extension should not be able to crash the gnome-shell, so I believe the issue should be fixed in the gnome shell.
