STEPS TO REPRODUCE 1. Install kubuntu. 2. Login into wayland 3. Install `plasma-discover-backend-flatpak` 4. Install some gtk app from flatpak 5. Gtk theme, cursor theme not applied to app OBSERVED RESULT Gtk theme, cursor theme not applied to app. EXPECTED RESULT Gtk theme, cursor theme applied to app. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 20.10 (available in About System) KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.74.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION https://bugs.launchpad.net/ubuntu/+source/kubuntu-meta/+bug/1915714
That's not a bad idea.
I don't really understand. You should be using xdg-desktop-portal-kde on Kubuntu. Maybe there's a problem in xdg-desktop-portal-kde that you're workarounding by running the -gtk counterpart?

I don't know, right now xdg-desktop-portal-kde cannot do what xdg-desktop-portal-gtk can do.
Even if installing the -gtk portal was the solution, making discover depend on it is the wrong approach given it's not needed to use flatpak apps
xdg-desktop-portal-gtk is now preinstalled in kubuntu.
