Thank you for the bug report! However Plasma 5.20.5 is no longer supported by KDE; supported versions are 5.24, and 5.26 or newer. Your distribution is responsible for providing support for older versions of KDE software. Please do one of the following: - Upgrade to a supported version and see if the issue is still relevant - Report the issue to your distribution
