Steam Input doesn't work with some games in Big Picutre mode

Hi, I detected that Steam Input doesn't work with some games if Big Picture is enabled, but it works with the Steam client in desktop mode.

Some of the games affected are the native version for Linux of BallisticNG and Split/Second (this one is only for Windows). I use Proton 9.0-3 and the Steam version is 1731433018 obtained from the Flatpak launcher. My operating system is now Fedora Silverblue 41 with the Wayland session on GNOME 47.1.

I tried a DualShock 4 and an 8Bitdo Ultimate 2.4G Wireless and I have the same result. This is my first the day with the 8BitDo controller, but I'm very sure that I could use my DualShock 4 with Steam Input in Big Picture mode previously with BallisticNG and Split/Second. I prefer to use Big Picture because I usually play with a controller.

I see that the version of steam-devices provided by RPM Fusion is 1.0.0.82, while the Flatpak launcher is in the version 1.0.0.81.
