I had the same problem. The fix only works partially, the settings menu launches, but when launching the game from there, there is a black screen. Any thoughts? Thanks!

P.S.: Using Arch as well, the output does not differ from the one without the fix. Looks like the interesting part of the output is not being shown...

I don't know if there were any updates since last posts, but I got pleasantly surprised to find out that Linux versions of both games work flawlessly on Arch.
