Spec

I’m using the latest versions of fedora and kde plasma.

How

When I put my laptop to sleep or it has put it’s self to sleep and i open it after a while, the taskbar and background vanishes sometimes but everything else functions normaly.

I hope my feedback can help.

What I suspect happens, is that the plasma shell crashes when the screen gets (un)locked.

I observed the same thing with both Fedora and EndeavourOS (Arch).

But to me the added piece of the puzzle is that this usually happens when I have my laptop connected to an external monitor and the laptop lid closed. Do you have a similar set-up or what?

Having the same issue here. kquitapp6 plasmashell && kstart plasmashell is a workaround.

I think this is the relevant part of the plasmashell log:

Same issue here, I have two monitors and it often happens that the secondary monitor would be partially black after waken up from sleep.

I think it’s due to plasmashell crash, restarting plasmashell as mentioned by @ixjlyons worked for me. For my case, plasmashell is caused by one of my widgets (dictionary), I also found other posts mentioning the dictionary widget to cause crashes, maybe you could check this.
