Ubuntu x86_64 18.04 with the 4.19.0-999 generic kernel, padoka ppa, on an AMD RX580 4gig w/ RADV llvm 8.0.0 Mesa 18.3.0-devel (git-686ec97cfb).
Launched game and it ran fine, maybe slightly faster than in windows even.
Only issue is that in fullscreen you will get flickering edges on the right and bottom.
