This somehow looks like a corruption in the plasmashell context (gkrellm looks translucent but w/o impact on the artifact structure)

Can you please leave some opaque window (empty kwrite will do) open when logging out and take a screenshot of that?

The trigger though is most likely the full scene blur filter in the logout effect - add

[Effect-Logout]
UseBlur=false


somewhere in ~/.config/kwinrc (resp. alter a present entry, if any)

That's fix the issue

I can't reproduce this anymore, so closing
