Do you have the latest version of KF5? There were fixes to menu positoning.
(In reply to Eike Hein from comment #1) > Do you have the latest version of KF5? There were fixes to menu positoning. It would seem not, but the bug did not occur until updating to Plasma 5.7.
Just got the update to KF5 from the Arch repos. The problem no longer occurs, but a new bug has arrived, which I will make a separate report for.
OK, please do.
