Log files? Apitrace?
Note that there is no difference between Borderless and regular Fullscreen on Linux.
Edit: According to two other users, Fullscreen works fine for them, both with DXVK's DXGI implementation and with Wine's.
Closing. No logs -> can't do anything, and other users cannot reproduce the problem.

The issue I'm having is that I can't get the game in fullscreen mode. Game runs on borderless window and windowed but it won't go fullscreen, it gets at 1600x900 rectangle with black borders all around. Want to try fullscreen because borderless window gives me 20% less FPS than windowed. I have to run the game windowed to get some good FPS.
