[Bug]: Floating armor around the player when using shaders

[D3K4P1T4T0R3]

Bug Description

With Iris, using any kind of shader (that has shadows) with a custom Vanity armor creates a doubled armor layer that floats around the player and moves around him as he walks around and turns his camera.

Disabling shadows in the shader option stops the problem.
This problem doesn't happen with any other mod. It also happens when I have no other mods than Iris and Vanity.

It's probably some kind of rendering steps problem in the HumanoidArmorLayerMixin.java files (I tried downloading the repo and fixing it myself, but I can't get a working build out of it for the life of me).

How to Reproduce?

1. Install Iris
2. Download any kind of shader with shadows.
3. In the game, get yourself a piece of armor with a custom skin from the Vanity mod.
4. See as a double of the armor you wear floats around you.
