Not the same thing; sorry for the inappropriate duplication.

Can you clarify what you mean by "receiver"?
Comment 3 Aleix Pol 2022-09-19 22:30:46 UTC 
I have never seen something like this, this would need some more investigation to be able to take action. It may as well be any other part of the stack that is broken, from graphics drivers to the greeter.

Can you test with a newer Plasma version and see if it has been addressed?
