ADDITIONAL INFORMATION
Comment 1 Nicolas Fella 2021-03-06 16:43:58 UTC 
Are you using X11 or Wayland?
Comment 2 German P 2021-03-06 19:30:59 UTC 
This happens only on wayland.
Comment 3 Marco Martin 2021-03-08 16:19:44 UTC 
I've seen it happenin as well, kindof a race condition as we can't set the window type early enough. is the same reason why in plasma mobile sometimes thewindow layer that shows the running tasks gets listed in itself
Comment 4 Nate Graham 2021-03-08 19:11:46 UTC 
Cannot reproduce, but it reminds me of Bug 403243. Perhaps they could be somehow related.
Comment 5 German P 2021-03-08 20:25:18 UTC 
It is fixed, this was the problem:
Manjaro's plasma-desktop package doesn't include:
plasma-wayland-session
kwayland-integration
plasma-wayland-protocols

Missing some of this packages make plasma wayland work but with weird behaviour (the widgets in the taskbar is just one of many).
Comment 6 Nate Graham 2021-03-08 20:42:12 UTC 
That would be problematic, yeah. Please do report this to the Manjaro packagers so they can include the necessary packages. Other users using the Plasma Wayland session on Manjaro will benefit as well.
