Bobbing causes weird shift in lighting

[Cervator]

What you were trying to do

Test something unrelated. One would normally expect to be able to move around the world with consistent lighting/shadows

What actually happened

Only when walking with the "bobbing" gfx turned on: the lighting shifts subtly for each "bob" (every few steps). Doesn't happen if flying or if you turn off the effect.

How to reproduce

• Run game normally and enter a world with "bobbing" enabled
• Move forward, ideally with a hill or something in front of you
• Observe subtle lighting shifts in tune with the head bobbing

Note:: It may be specific to time of day in-game - seemed to not happen in some cases but around World Time 0.5 it was strongly present.

It may relate to the recent JOML changes as I cannot replicate with the commit immediately preceding #3811 - but I haven't tested after that point commit-by-commit. @PS-Soundwave suspected as much, but upgrading to 1.9.23 from 1.9.19 didn't seem to have an effect.

Screenies

Easier to see the effect in-game, but it is there

I think #3885 resolves this.

Looks like! Thanks hunting it down :-)
