external screen looses background and panel after sleep/lock

[Sbob]

Hi all;

I'm running Fedora 38 on a new LG Gram 17, I have an external monitor 
via HDMI cable.

When the screens have gone to sleep and I wake them, I have lost the 
background and panel on the external monitor. I can unplug the hdmi 
cable and plug it back in to fix, but... Its a pain

Any Ideas? Is my monitor going bad?

Late to respond.

Does anything show up in the journal regarding the monitor?

If I restart plasma, I get messages in the terminal window about kwin 
calls.  Something may show up that way.

kquitapp5 plasmashell && kstart5 plasmashell &

The command may also bring the background and panels back.
