Valve completely redesigned Big Picture Mode for Steam Deck and SteamOS. They’ve been porting those changes over to Desktop Steam and even changing Desktop Steam’s UI slowly to match and make everything more consistant.

Disclaimer: I have a theme mod installed which changes the color of some elements. Layout is the same though.
No. A lot of the stuff GamePass uses on Windows, like UWP, haven’t been reverse engineered yet. And it doesn’t seem like there’s much interest to do so, outside of the occasional GamePass subscriber that wants to use Linux like yourself. Cloud Streaming with GamePass Ultimate is your only real option currently. And at best you can maybe hope that Microsoft will partner with Steam in the future to integrate it there in some way, similar to EA Play.
Yeah, but they’re coming to Desktop stable soon. Or you can switch to Beta and try them out. It’s up to you. Just wanted to show that Valve is addressing the issues with Big Picture Mode.
