I don't recall ever touching Flatpak settings, apart from another app, RetroDeck. However, when I looked at Flatpak privileges via Flatseal there were some non-default values for Steam (shown via the "!" icon near the toggle with hovertext "Changed by the user"). Resetting it fixed this issue for me.

If anyone sees the "!" it would be a good idea to note in a comment what toggles have it to identify root cause and maybe figure out a permanent fix.

Also having this issue on openSUSE Tumbleweed with Flatpak 1.14.4. Native Steam works fine.

Anyone having this should double-check if they have global overrides that also affect this app. Sandbox holes that expose host user home are not supported.

So in doing a new system build on Fedora Silverblue and Kinoite again, I discovered I may have actually been the one to have changed the default flatpak permissions. I couldn't get controller input to be recognized within games (worked fine in Big Picture mode) in wired or wireless modes. The solution to my controller issue was to enable access to D-Bus system bus / socket=system-bus in Flatseal. It's possible I didn't do this, but I tried a relatively exhaustive list of things like making sure of things like Steam settings around controllers, and various suggestions found in #734

As I'm mildly confident this is what happened which is technically deviating from the official flatpak permissions that causes this issue, I'm closing my issue. For those also deviating to get Steam controller support, I suggest pushing for better controller support in one of the several open controller issues
