The majority of “Linux issues” is created intentionally. It’s often not enough to not support Linux officially (even if there would be no additional work involved anyway) and let players figure out problems on their own. A lot of studios, publishers and developers actually go out of their way and actively invest time to block Linux.
So nothing will obviously change. Windows could run on a fully compatible Linux kernel tomorrow and games would still check for Linux to artificially create issues.
You could…
But then one is an open system where you can disable the UI put on top and have a working linux system, while the other is a closed blob destroying compatibility and trying hard to lock you out from accessing the underlying linux system.
