Thanks for the report MiXiM. I've just tested on plasmashell 5.20.3 and I am unable to replicate this issue.

Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I'm setting status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.

Never occured a long time ... probably not a bug
