probably upstream

Comment 2 Eike Hein 2016-06-16 23:22:15 UTC

Plasma 5.7 ships a fully-rewritten Task Manager backend which should resolve these issues. Please re-test with the Plasma 5.7 final release and feel free to reopen if problems do persist after all.

Comment 3 Aayush Agarwal 2016-06-16 23:29:00 UTC

Thanks, I'll test it as soon as my distro ships the new version.
