Dear Maintainer,

when I start KDE systemsettings in my Gnome session, nothing happens. Or rather, a new entry appears in the window list, but no window.
On the terminal, I see:

$ systemsettings
kf.kirigami.platform: Failed to find a Kirigami platform plugin for style "Fusion"
qt.qpa.wayland: eglSwapBuffers failed with 0x300d, surface: 0x0

This is with QT_QPA_PLATFORMTHEME unset, though I also tried setting it to qt5ct to no avail.

Starting KDE systemsettings in a Gnome session can still make sense to configure KDE applications.

Other KDE applications work correctly. (Well, they start. They generally look pretty terrible as none of the icons are showing up, but that's a different problem.)

Kind regards,
Ralf
