Specifically it crashes after clicking "Show Desktop" in the panel (which actually doesn't show the desktop?) and then running "plasmashell --replace" I could reproduce with those steps. Should only affect Plasma 6. A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/4138 Git commit cf2410f6312697ef86312a391c12ebe329a2e6d1 by Vlad Zahorodnii, on behalf of David Edmundson. Committed on 26/05/2023 at 08:30. Pushed by vladz into branch 'master'. Guard updateLayer for deleted windows When a window is deleted it all "set" operations should no-op. As for the bug specifically, we have an effect that keeps the desktop alive. If a user calls showDesktop not only do we not update the stacking order, we also call updateLayer when the client closes this is after the window is in the deleted state.
