Plasma panel disappears after unlock

Using Fedora 44 KDE Plasma laptop completely up-to-date. I’m having a consistent problem I am unable to solve:

When I connect the laptop to an external monitor and close laptop’s lid, everything works ok, I select “External monitor only” and ok.

But when I leave the laptop inactive long enough to turn the output off (powersaving), when I go back, session is locked and when I type the password, the panel is gone. Notifications appear in random places and plasma menu itself too.

The only way I find to restore it either by disconnect and reattach HDMI cable or by running plasmashell --replace

This happens in my two laptops.

I know a long standing bug in Plasma existed some versions before, but it should be fixed by now.

Anyone having this problem?

Thank you very much

Best regards
Miguel
