Bug Description

 - No more system tray notifications
 - System tray lost most items (actually, all except KMail widget)
 - No more Add Panel option in the desktop menu
 - Configure Desktop menu option hangs with the error message "Layout changes must be applied before other changes can be made"; clicking Apply button does nothing
 - No amount of Default selections made in the System Settings would fix the above issues
 - Same issues for new user except the desktop starts in completely bare state (no panel at all) and there is no way to configure it due to the above bugs

More things which stopped working:

  - Multimedia buttons/controls on my Logitech G610 USB keyboard (used to work perfectly)
  - Media player control applet disappeared, its keyboard shortcut does nothing now

The same set of problems with 5.12 update is currently being discussed / debugged on KaOS list:

https://forum.kaosx.us/d/2147-issues-with-last-update-plasma-5-12

So far, there's been little progress, as far as I understand. Maybe it makes sense joining efforts with upstream maintainers?

I can confirm that all issues mentioned in the above thread occur on my system as well.

Still the same bug persists after today's update to Plasma 5.12.1 / KDE 5.43.0:

  - No desktop panel
  - No way to add a new panel to the desktop
  - Configure Desktop command stuck at the first (Wallpapers) tab with "Layout changes must be applied..." message but no changes can be applied

And this is the same issues reported for ArchLinux:

https://bbs.archlinux.org/viewtopic.php?id=234332

However, I have tried the solution suggested (switching Display manager from SDDM to LighDM) and it did not work for me at all.

I also found this same issue reported on OpenSUSE forum. You can find more reports by running Google search for the error message string: "Layout changes must be applied before other changes cam be made."

Since this seems to be a Plasma issue rather than a Kubuntu/ubuntu issue, the useful place to report this situation is bugs.kde.org.

I personally upgraded and experienced none of the issues in the bug report, so I can't report this upstream to KDE.
