When a WindowPreview is being destroyed, the class default handler for the `destroy` signal is responsible for destroying its child actors. This happens after the emission of the `destroy` signal, i.e. after `WindowPreview::_onDestroy()` has been run. The destruction of the WindowPreview's child actors now triggers a re-pick, but due to WindowPreview having already being marked as `CLUTTER_IN_DESTRUCTION`, it will not be picked, resulting in a `leave` event if the cursor was on top of the WindowPreview at the time `destroy()` was called on it. So this leads to `WindowPreview::vfunc_leave_event()` being run after `WindowPreview::_onDestroy()`, which means the idle started by the leave event handler will not be removed and ends up accessing actors after they have already been destroyed.

Bugs should be reported to the GNOME bug tracking system. Please refer to the Schedule wiki page to see the supported versions.
Contributing
To contribute, open merge requests at https://gitlab.gnome.org/GNOME/gnome-shell.
Commit messages should follow the GNOME commit message
guidelines. If a merge request
fixes an existing issue, it is good practice to append the full issue URL
to each commit message. Try to always prefix commit subjects with a relevant
topic, such as panel: or status/network:, and it's always better to write
too much in the commit message body than too little.
Default branch
The default development branch is main. If you still have a local
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
