Bazzite has been astoundingly good for me. The only games that have issues are usually those with kernel-level anti-cheat and tbh I wouldn't play those anyways if I was running Windows (although I understand that's a deal breaker for some).
Support for Bazzite is fantastic too. Kyle and the rest of the folks on Discord are amazing!
Or just use Bazzite. Already supports multiple handhelds, desktop, and you can have the same exact experience of opening into big picture like the Steamdeck if you'd like.
Even just being rooted on the stock Pixel rom is a fight. It's a constant cat and mouse game to pass basic and device integrity, but as of recently a lot of us have been able to pass strong integrity as well which has been nice.
I switched to Bazzite about 1/2 a year ago and haven't looked backed. Better performance, more stable, I can do dev work that I'm used to without WSL and such.
The best part is I have absolutely 0 incentive to play games that come with a kernel-level rootkit anticheat too!
Rooting your phone if possible is always a nice solution to this. BCR works great for me(along with BCR GUI). I can also still use my banking and Google wallet apps (you just need the right apps/modules)
If this is enabled by default it'll certainly be needed, especially in cases like multitasking.
