This is z-fighting that occurs because the game relies on two different vertex shaders to produce the same numerical values. I'm not sure if this can be fixed.
FWIW it doesn't happen with amdvlk, but that's probably just luck and can break any time.
Edit: I tried declaring the vertex positions as invariant, which fixes the problem on AMD but is known to break some other games on Nvidia for unknown reasons.
Edit 2: Fixed on RADV, not sure if this happens on Nvidia.
I wonder if this might be also beneficial for this radv Just Cause 3 issue:

Doubt it since that issue is over a year old, whereas the NIR optimizations that break our stuff are very recent.
I can confirm in-game that it is indeed resolved. Thanks for the quick fix!

Game shows massive amount of artifacts on distant (and sometimes nearby) terrain and flickers as the camera moves, which isn't present with Wine's own D3D11 implementation. No other rendering issues except this one. Unfortunately it is very laggy (<0.3 fps) and takes nearly half an hour to load during API tracing so I only traced the minimal frames to show the bug with the login portion trimmed.
