Created attachment 154893 [details] I've attached a pic of my main tray panel to see if anything might be interfering with the system tray. Deadbeef, Tomboy, and Evolution in KDocker should be there on the tray. SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Open some apps that can reside on the system tray as icons, like Tomboy, Deadbeef, KDocker, KTorrent etc. OBSERVED RESULT The icons of opened applications sometimes doesn't even appear at first, and almost always disappearing after a while (not just getting hidden, really disappearing). EXPECTED RESULT To see the tray icons of running applications according to the system tray settings, visible or hidden, but being there on the tray. SOFTWARE/OS VERSIONS Linux: Debian Testing (Bookworm/Sid) KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION Tried to remove and re-add system tray, but the problem persisted.
Can you, when the icons are gone, run "systemctl --user status plasma-kded" and show the result here?

Do you need any more info to resolve this issue? It's pretty annoying to live with this bug...
