Hi Aurélien, thank you for your quick reply.
There are many people running testing and/or unstable, me included, for whom this bug doesn't happen. So we'll need a bit more analysis if we want to get it fixed. Could you try creating a new user (without an existing $HOME directory) on one of the machines where you see the bug and report back if the new user still has the issue ?
I created a new user via `adduser` and the problem persisted for it. Interestingly, that user had a black background and not some default background image. The .xsession-errors contains some complaints about missing /home/kdetest.config/kdedefaults, but I did not try to resolve this.
Also can you find anything meaningful in the system log at the time where you right click or during the load of the user session ?

QPixmap: QGuiApplication must be created before calling defaultDepth(). Neither `journalctl` nor `sudo journalctl` show anything of interest after right clicking somewhere. Are there other logs I should have a look at?
Lastly if you could have a look at the upstream bugs.kde.org platform and look for a similar bug report that would be useful. I'll have a look too when I can.
I will do so and report if I find something. Best Max Görner
