A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/197 Git commit 8d33d2d7372308d0b1f4d3ab7af645ebe9677e83 by David Edmundson. Committed on 22/10/2020 at 11:49. Pushed by davidedmundson into branch 'master'. [kcms/activities] Port to QQuickWidget from nested QQuickWindows Nested QQuickWindows are still somewhat problematic especially when used in systemsettings which is already a very hybrid mix. At some point this will all be fully ported to QtQuick anyway, there isn't anything especially complex going on in the UI that isn't QtQuick already. This is a small backportable patch to supress the bugs.

STEPS TO REPRODUCE 1. open system settings > workspace behavior > activities on Wayland 2. switch to another section (Virtual desktops, general behavior, etc) 3.
