Created attachment 123188 [details] screenshot SUMMARY On neon unstable edition I see a hamburger button aside the header of several KCMs, no menu opens when such button is clicked. My screenshot shows "global theme" KCM, but the following KCMs are also affected: plasma style window decorations colors fonts icons cursors general behavior desktop effects virtual desktops boot splash screen splash screen file search notifications language launch feedback user feedback display configuration night colors audio Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.17.80 KDE Frameworks Version: 5.64.0 Qt Version: 5.13.1
Strange. Cannot reproduce.
This is fixed with https://phabricator.kde.org/D24607
I had a feeling you would know!
