Your Expectation

Mouse sensitivity to remain the same throughout the game

The Reality

Mouse sensitivity accelerates when holding down mouse 1 or 2 and looking around (mining, farming, etc)

Reproduce: Set your sensitivity and get used to it, then look around while holding mouse 1 or 2 and notice how it accelerates (a lot)

Mouse acceleration, pointer precision, and anything related is of course disabled throughout windows settings and driver software

Testing polling rates (present on all):
1000Hz/1ms
500Hz/2ms
250Hz/4ms

Your Proposal

I assume some mod is doing this but cannot find anything about it

Can you try turning on raw mouse input in lwjgl3ify.cfg (or in the in-game mod config for lwjgl3ify) and see if that helps?

This feature will expire after each restart of the game.

This was indeed the cause, and it does expire after restart. If you set to false before starting and change it in the in-game config every time it does solve the problem, but definitely very annoying.
