Created attachment 155071 [details] My Desktop after reboot SUMMARY On each reboot, multiple instances of the Clipboard widget icon appear in the system tray and one appears on the desktop. STEPS TO REPRODUCE Boot the machine. OBSERVED RESULT Since I upgraded my desktop machine to Kubuntu 22.10, I have had this extremely annoying problem. Initially, the 'Clipboard' icon in the system tray was not present. AFAICR, this had always been present in previous versions (Maybe I explicitly installed it many years ago and it had always been carried over during upgrades). Anyway it was found MIA. Using the 'Add Widgets' menu item I got it back, but I now have no less than 6 instances running (five in the system tray and one on the desktop, see screenshot attached. EXPECTED RESULT Only one Clipboard icon in the system tray SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.19.0-26 / 5.26.4 (available in About System) KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.100.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION I initially raised this as a question on 'Ubuntu Answers' and then raised it as a bug on Launchpad, but have yet to receive any helpful responses. Also, this may be irrelevant, but I have noticed another error that I have not seen before. I found that the audio player Clementine appeared a bit buggy since I installed 22.10 and after a bit of research I found that it was no longer supported. I therefore removed it and installed Strawberry. This works fine, but I cannot make it remember which Activity I want it to start in; it always starts in whatever Activity I was in when I shut down the previous session. Looking at the preferences file for plasma, I see that the modified time is equivalent to when I rebooted and not when I moved strawberry from my Games Activity to my Multimedia Activity.
>On each reboot, multiple instances of the Clipboard widget icon appear in the system tray and one appears on the desktop. And do they stay gone after you remove them on the next reboot?
They come back at the next reboot, so it is a daily task.
If you add/remove any other applet does that change persist?
No. I removed the Networks widget, rebooted and the icon was back again.
Since there had been no feedback on this, I decided to do a clean installation of 22.10 instead of relying on the upgrade that I did last year. When this was complete, I found exactly the same problem. I then decided to do another clean installation of 22.10; this time all on the same partition, instead of my usual setup of OS on sda and /home on sdb. This installed OK, but the same bug was apparent. This problem doesn't seem to be confined to the one system. I have now fallen back on my laptop which I rarely use these days, but is also at 22.10. It shows the same problem.
We don't have many other duplicate reports. can I have your ~/.config/plasma-org.kde.plasma.desktop-appletsrc and ~/.config/plasmashellrc

Files added as requested. These are from my laptop, because I had a serious bug when trying to regress the desktop to 22.04 and cannot get into it yet.
Created attachment 155305 [details] Before and After files I have now got my desktop working again and in the attached .zip file I have include the two requested files from this machine instead of my laptop. In the directory 'Freshly_Booted' there are many instances of the Clipboard icon in the System Tray and one instance of the Clipboard in the Internet Activity. Also, the running instance of the 'Strawberry' music player appears in the 'Utilities' Activity instead of the 'Multimedia' one. Finally (and this is new), the 'Control Centre' widget is displaced on one of the Activities. In the directory 'Desktop_Cleaned' all this has been restored to the proper arrangement. You will see from the screenshot of the output of kdiff that there are very few changes resulting from the cleanup operation. I hope this helps.
