--- Comment #4 from Lectrode electrodexsnet@gmail.com --- Thank you for looking into this. Interesting. Yes, Manjaro sets that (not sure about Arch). I will test this once I'm off work in a few hours and let you know if that makes a difference.
Btw, I had tested this issue again with both wine and wine-staging 4.16 before the new rockstar launcher, and this issue still existed. The latest Proton adds patches that get the new launcher working, so I'll test with that first.
If I need updated wine logs, I'll need to add the couple launcher patches and get that compiled.
