Can't reproduce it on master. What I tried was locking my session, sending myself email and waiting for the KMail notification ding, then unlock my session and open the notification panel. Operating System: Fedora Linux 40 KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.1.0 Qt Version: 6.6.2 Kernel Version: 6.8.2-300.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 6600 Hm, now I can reproduce this! I have no idea what causes it, but I did not have to lock my screen to make it happen. Will keep investigating. My backtrace

See Bug 413782 and Bug 456947 which were previous cases of ShellCorona::screenInvariants() causing a crash. Sentry says this instance of it is in the top 15 of all Plasma crashes. Seems like a particularly buggy component. We believe this is fixed in 6.2, lets close this and track on Sentry It's not; Sentry just got a crash from 6.2.1: https://crash-reports.kde.org/organizations/kde/issues/6066/events/4be2fa61f5514369a3b3e0028fccf10c/?referrer=user-feedback A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4900 Git commit 08174d25e0a12f385da4ae11e960eb7d12e3fa0f by Marco Martin. Committed on 15/11/2024 at 14:57. Pushed by mart into branch 'master'. X11/multiscreen: Always emit outputOrderChanged when a screen is disconnected Don't remove immediately the output from m_outputOrder. This fixes screen removal both the "normal" case and the case of last screen removed that causes the last QScreen to become ":0.0" named. Why the current master was broken: In X11OutputOrderWatcher when a screen is disconnected it removes immediately the screen from m_outputOrder, but then on the timecompressed check in refresh() the outputorderchanged is emitted by comparing with m_outputOrder which is "new" already, so the signal is not emitted. This makes plasma not remove the corresponding DesktopView (and panels) staying with an inconsistent internal state, either failing screenInvariants() or ending up with wrong desktops and panels on wrong screen if invariants are disabled M +3 -17 libkworkspace/outputorderwatcher.cpp https://invent.kde.org/plasma/plasma-workspace/-/commit/08174d25e0a12f385da4ae11e960eb7d12e3fa0f A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4917 Git commit eb1896d2df36e7f6945df8d3c615a924a15cb536 by Marco Martin.

SUMMARY After unlocking my desktop, I tried to click on the notification applet which resulted in some stutter before Plasmashell crashed. I'm unsure if the following steps can reproduce it. STEPS TO REPRODUCE 1. Lock desktop 2. Unlock desktop 3. Click on notification applet if present OBSERVED RESULT Notification applet opens without crashing Plasmashell EXPECTED RESULT Plasmashell crashes.
