I’m not a game dev, but a dev. To me this is not a best practice issue but more a “shouldn’t be possible” issue. This is how exploits and hacks happen by making elevated permissions possible.
Maybe there is something else as play rather than what’s been described, but if accurate it’s a major security issue.
If game pass is only viable from stream, I’ll probably skip but will research some more
I actually managed to get the attention of a Valve employee, who is going to pull the logs from my and the wife's accounts, as in his own words, this shouldn't have happened.
"This should not have happened. Steam should detect that another Steam account's files were there - it's in the proton equivalent of the Windows userdata /AppData/LocalLow/ folder - and save them off to a special location (Steam's own userdata/<accountid>/ folder), then restore them when that user logged back in to Steam and ran the game.
We fixed this a couple of years ago because it already affected Windows as well - if you changed Steam account but not Windows user.
I've requested the system pull up logs from your account and can take a look when they come in. Though it may be that there's more interesting data in the logs from your wife's account - feel free to email me (XXX @ XXX) with both account names (just in case) and I'll take a look."
Given there are people in recent weeks and months in some of the threads elsewhere mentioning this isn't fixed yet, it doesn't sound like the issue is completely resolved yet, and may be more of a work in progress than they want to admit
