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.

Hi, chiming in to say I’m also having this issue with pretty much the same conditions: using the latest version of Fedora and KDE, with an external monitor as my primary screen, and having the plasma shell crash when waking from sleep.
Would love to hear any updates on this.
