At least I have found a workaround in your link: install gnome-settings-daemon
package.

If it's about apps, it sure isn't about our flatpak runtime. If installing a component fixes it, it's either a gtk issue or an issue from your distro misdetecting dependencies.

Marking as a downstream issue, please reopen if you think I missed something.

Possible workaround: xdg-desktop-portal-gtk.

For what it's worth, it still happens to me even with xdg-desktop-portal-gtk installed, so I guess it is just a real downstream issue.

I just had this issue, and installed xdg-desktop-portal-gtk, and it seemed it didn't work, but after restarting systemctl --user xdg-desktop-portal it works ( if one does not restart it, it doesn't work ).

Hope it helps !
