To ensure games run well on Linux either via Native Linux builds or Windows games with Proton, part of the magic is in the Steam Linux Runtime. A new version of it, the Steam Linux Runtime 4.0 was recently put up with some pretty big changes.
What’s the point of it? It ensures Steam and games run through Steam on Linux work properly across all the many different Linux distributions. Another secret Valve sauce for Linux. Well, not secret at all but you get my meaning I’m sure.
I just run Steam as a flatpak. Works fine.
Not sure why the downvotes. Flatpak is a great thing.
Unless you muck around in bottles a lot of things break.
What does “muck around in bottles” mean?
Flatpacks have permission issues due to the way they are structurally designed. Applications like Flatseal and Bottles allow you to remove those limitations, but it’s a lot easier to just install the client outside of Flatpack.
I’ve only had to use Flatseal a couple times to fix wonky permissions for Flatpaks, and I’m not even sure what Bottles has to do with them since Wine has nothing to do with Flatpak to the best of my knowledge
Bottles is an app that people who use hyperland also use, but I don’t know what it does.
It’s basically a GUI interface for wine
It doesn’t work fine out of the box. I tried it on Opensuse MicroOS a year and a bit ago and had to search 3-5 pretty undocumented solutions to big problems before being able to play the same games that non-flatpak could.
Out of the box, proton didn’t work at all.
Sometimes you have to allow access to some things outside of the Flatpak container. I use Flatseal for that.
I don’t think flatseal can set the background permission, but I might not recall correctly:
