Then please don't ask for help from anywhere outside of Steam support, and certainly never blame Linux for any issues you come up against with your non-native game(s). If you face any issues with your Windows game on Linux, that is not Linux's fault or problem.
It destroys any incentive for game houses to develop native Linux versions of their games, leaving Linux gaming in an permanent almost as good state, and prevents integrations with chat apps and so on. Why promote a poorer experience for users?
Wow, got downvoted for giving practical diagnostic advice. Someone out there is a Proton fanboy who can't admit this is a valid thing to test to help finding root cause.
Please try some Linux native games and see if they have the same issue. If not, it would be a WINE/Proton issue and then the problem would belong to them. If it happens on Linux native games, then it's a Linux issue.
This is the primary reason I dislike WINE/Proton... ambiguity as to whether it's the WINE/Proton compatibility layer or the Linux distro itself.
The question was specific to systemd-homed. Jumping to why isn't FDE good enough for you isn't even logical. Sure they changed direction later, but it is not what was originally asked. In answering the primary question, additional questions from the OP may have arisen, which is fine. What is not fine is to assume incompetence from the start, which is what ya'll were doing.
Wth kid. I stick up for you against someone assuming you don't know anything, and then you stick your hand up and say you actually don't? Fine, you deserve one another.
For the record, if you can afford the performance hit and are on SSD, I recommend either LUKS FDE or filesystem based encryption (ZFS, for example) + Home directory encryption. Don't forget to encrypt the swap, too. That way if you ever have to share the FDE passphrase with someone you share a computer with, your data in your home directory is still safe, and it can encrypt the filenames, too. If you're on spinning disk, you can still go that hard, but it'll be noticeably slower.
FDE is fine for most work computers. Home directory encryption is for shared computers, or to stack on FDE if you're sufficiently paranoid.
