Created attachment 181027 [details] system logs seen on waking up from hibernation SUMMARY When Plasma on my laptop is configured to use an external monitor as the main input, it reliably disappears after the system wakes up from hibernation. There is a black bar where I would expect Plasma's tray to be. After `killall plasmashell && kstart plasmashell` , it becomes available once again. STEPS TO REPRODUCE 1. On a laptop, configure Plasma to use an external monitor as the main input. 2. Trigger hibernation/sleep. 3. Wake up the system. OBSERVED RESULT Plasma's tray will likely be gone. EXPECTED RESULT Plasma's tray should be where I left it. SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 Kernel Version: 6.14.5-300.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 20 × 13th Gen Intel® Core™ i7-1370P Memory: 62.4 GiB of RAM Graphics Processor: Intel® Iris® Xe Graphics Model: ThinkPad X1 Carbon Gen 11 ADDITIONAL INFORMATION See attachment for system logs seen on waking up from hibernation. Removing the notification widget from the tray doesn't seem to have fully fixed the issue, and it's not an ideal solution anyways because its absence causes any notification to hang the whole desktop for several seconds.

(In reply to Nate Graham from comment #1) > > *** This bug has been marked as a duplicate of bug 494262 *** Thanks for the quick triage! I just wanted to clarify something - in my case, the application windows remain visible on the external monitor, it's only the system tray and wallpaper that disappear. It also only seems to occur when waking up from hibernation - a simple screen lock - standby - unlock sequence doesn't seem to trigger it.
Yep, that's the same issue indeed. Windows are drawn by KWin, not Plasma.
