Hello! Plasma 4 was replaced by Plasma 5 four years ago by the KDE community. In that time we have made great strides in stability and functionality. We are closing all Plasma 4 bugs as most of them are no longer applicable to the new frameworks Plasma 5 is built upon. If you could, please re-test with the latest version of Plasma 5, and submit a new bug to "plasmashell" if you continue to have an issue. Thank you!
