SUMMARY When setting `kcm_lookandfeel` to `false` in `/etc/xdg/kdeglobals`, the setting for global themes in Colors & Themes is hidden, which is intended. However in "Quick Settings" the option for "Global Theme" is still visible, but clicking on the button does in fact do nothing. STEPS TO REPRODUCE 1. Set `kcm_lookandfeel` to `false` in `/etc/xdg/kdeglobals` 2. logout and login again (or "restart" plasmashell via `killall plasmashell; kstart plasmashell`) 3. open "System Settings" and navigate to "Quick Settings" OBSERVED RESULT Under "More appearance settings", "Global Theme" is still visible EXPECTED RESULT Under "More appearance settings", "Global Theme" should also be hidden like in "Colors & Themes" SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux 6.17.5 KDE Plasma Version: 6.5.0 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 ADDITIONAL INFORMATION
