xdg-desktop-portal-gtk VS org.signal.Signal

I came across this, could this be playing a role? If it fixes Fedora 37 then it would be a clue and perhaps then the package could enter the string itself? https://github.com/flatpak/xdg-desktop-portal-gtk/issues/72

However, the actual dialogs and access points are provided by a backend, which differs from what desktop are you using. For example, Gnome uses xdg-desktop-portal-gtk, KDE uses xdg-desktop-portal-kde and so on.\ If there is an issue with the implementation of an portal, you need to find the backend you use and report it to them.

Is the Web search provider enabled in Settings? Those can apparently trigger background detection: https://github.com/flatpak/xdg-desktop-portal-gtk/issues/293

That sounds like https://github.com/flatpak/xdg-desktop-portal-gtk/issues/137

you still xdg-desktop-portal-wlr in sway for screen sharing. the purpose of the gtk portal on non-gnome setups is to pass through some gtk settings (e.g. fontconfig, aliasing, gtk theme) to flatpak apps. your gtk flatpak apps won't follow the system theme and fontconfig unless you have the xdg-desktop-portal-gtk installed. right now it's borked though see below for more details - https://bugs.archlinux.org/task/72686?project=1&string=xdg-desktop-portal-gtk - https://github.com/flatpak/xdg-desktop-portal-gtk/issues/360

The issue has been reported https://github.com/flathub/org.signal.Signal/issues/389

Your issue seems similar to this one on github.

Now look at Signal on Flathub. It is not by Signal themselves so an attack vector exists. The reason I mention it is because the Signal team got the Signal Snap removed.
