Why is my backgound totally black and why doesn't right-click work?

On Virtual Desktop 1, desktop backgrounds are OK and right-click works.

However, when I switch to Virtual Desktop 2, 3, 4, the background is totally black and right-click doesn’t do anything.

How can I fix this?

Also curious about this. Seems to happen occasionally when my screens come out of stand-by. Reboot fixes it temporarily.
Typically it affects only one of my 3 screens.

Same issue already posted months ago:

Still getting black screen on logon screen after switching to single monitor setup and reinstalling Manjaro KDE.
Something’s still wrong.

I also noticed that if you have multiple virtual desktops, in some virtual desktops, the desktop looks good with background and popup menu, but on some is black and no popup menu what is called as “Zombie Desktop” in KDE lingo.

In the image, desktop on Virtual Desktop 1 was OK, but not on Virtual Desktop 2, 3, and 4.
