Yes, it doesn't work out of the box. Proton games literally won't launch. You need to run this command (at least on atomic distros):

flatpak permission-set background background com.valvesoftware.Steam yes

Mangohud also doesn't work without modifications, as well as a couple games having absolutely abysmal framerates like rocket league.

Gamemode doesn't work AFAIK

It is a worse experience in general, but works for a lot of people.

This is what I hate about flatpak. I shouldn't have to just know what random permission something needs. It should be marked with what permissions it requires, and then prompt for whether or not to grant them when it's launched.

If the permission was necessary, the Flathub package would enable it by default. I can't remember ever having a bad experience with the Flathub package.
