Unfortunately I had to switch to windows for day-today work due to vpn restrictions. I can unfortunately not confirm if this bug is still happening.

It's been too long now, and I don't use that version of Plasma any more.

Hi,

thanks for your messages. Indeed, I do not think that this problem is of 
any more relevance now.
