Created attachment 142532 [details] screenshot SUMMARY When you click on the session termination button (in multiscreen configurations) all kscreenlocker open on one screen. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.23 KDE Plasma Version: 5.23.0 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.3
Affects the logout screen too. Seems to be a regression in how KWin positions full-screen overlays like this in multi-screen setups; moving there.
