Forgot to mention: this is on Wayland (and it's a regression wrt 5.22) A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/1483 Git commit 21da7b7ed801f7a9b826a5f1d6cb7d31be0c6f4b by Vlad Zahorodnii. Committed on 01/10/2021 at 08:07. Pushed by vladz into branch 'master'. effects/thumbnailaside: Fix crash in clientArea() clientArea() was changed to forbid "-1" screen ids, but it seems like the thumbnail aside effect can pass it to refer to the active screen. This change makes the thumbnail aside effect handle "-1" screen id case explicitly. It will be also useful for EffectScreen transition.
