Additional info bottom of main screen must be at the same line as bottom of additional screen and panel must be on bottom. Additional screen must be wider/have higher resolution.

Hi. Are you sure, it was duplicated? Reason of frozen is different: in my case it is connecting external screen.

Also: I see switching activities (by keyboard: SUPER+TAB) will unfreeze panels.

I see bug did not occur, when external screen is turn on before I log-in plasma desktop.

Can you tell, how to test I use version, which needed patches?

Sorry, the problem do not occur on Plasma6.1-pre-release, when external screen was plugged during device boot. On Plasma6-rc1, the problem still occur.
