Dupe of MC-111500 (although this one has a better description)

SunCat, does that mean it can stay or not?

A moderator should decide.

Why my bug report was resolved as duplicate when i first created this bug?!

Because this one is more descriptive.

Oh really!

Then it's not resolve as duplicate than as replaced.

Just to fix this bug as soon as possible, cause it's pretty annoying!

EDIT: Fixed a spelling error.

Do you have a cracked launcher?

CreepyEnderman No.

Can someone please test if this is still an issue? I can no longer reproduce this in 1.14.4.

It can still happen even at low speeds or almost not moving in the air with Slow Falling status effect.

As far as I am aware this is caused by the setupRotations function in PlayerRenderer turning some floating point number into NaN and in return it turns the transformation matrix into NaN causing it to not render.
