The following steps lead to a complete crash and logout of Gnome (steps tested on a fresh Fedora 39 installation):
- log in using Wayland (not Xorg);
- install and enable the Switcher extension;
- open a terminal, run "guake -p";
- in the "Main window" tab, check the "Hide on lose focus" option, close the preferences window;
- in another terminal, type "guake-toggle" to make the guake window appear;
- now the guake window has appeared, press Super+W to make the Switcher window appear;
- at this point the guake window has disappeared by itself, which is normal; press Esc to make the Switcher window disappear as well;
- repeat steps 5) and 6); now the crash occurs.
