Symptoms

Mouselook is completely erratic. Sensitivity is all over the place, sometimes being too low, and sometimes being too high, apart from movement itself being often jittery. It could be that maybe it's not grabbing the mouse correctly?

Reproduction

1. After choosing language and going through the various introductory text screens, wait until player movement is allowed.
2. Move the mouse to look around.

Start with the linked steam-429720.log and system information Gist, then reproduce the issue using Proton 4.2-9 after player movement becomes available. Done means mouselook sensitivity and movement are stable and predictable when moving the mouse, without erratic or jittery behavior.
