@forteller I doubt they ever implemented the FreeDesktop background portal, nobody even made the request: https://github.com/search?q=repo:qbittorrent/qBittorrent+background+portal
In comparison, people have made such requests for other apps, from what I can see:
* https://github.com/transmission/transmission/issues/5484
* https://gitlab.gnome.org/World/Fragments/-/issues/30#note_1909051
