Summary

Since #15697, mouse input feels somewhat bad. I can only move it in a coarse grid (in 0.6° steps it seems (this is also the my value of mouse_sensitivity)). And there also seems to be some mouse acceleration or whatever going on.

This is not game-breaking, and we had it like this before, so I guess it's not a blocker.

Steps to reproduce

Move your mouse to look around.

Haven't tested on non-SDL.

I also had to increase the mouse_sensitivity setting from 0.2 to 0.6, this might have an influence.
