Vivecraft rendering is broken when voxy is enabled

[Squeakychu]

When using Vivecraft's VR mode, rendering with voxy is currently broken. Below is a screenshot with normal Vivecraft gameplay. When voxy is disabled, water, hands, and GUI all render appropriately.

However, when voxy is enabled, water becomes severely glitched, either not rendering at all, or partially rendering with a lot of noise. The next two should hopefully show it a little bit. In motion, the water is noisy like static though. The water generated by voxy LODs render fine though. Other textures close by become noisy too, though they render fully at least.

Furthermore, when voxy is enabled, all GUI elements, including the players hands become invisible, making menu navigation impossible.

These issues only occur when VR mode is enabled. Regular 2d doesn't seem to exhibit any of the issues above with Voxy enabled.

Any news?

I see a lot of these messages in logs:
OpenGL debug message: id=1282, source=API, type=ERROR, severity=HIGH, message='GL_INVALID_OPERATION error generated. Depth formats do not match.'
when I use voxy and vivecraft

I disabled stencil on vivecraft side
https://github.com/Vivecraft/VivecraftMod/blob/Multiloader-1.20.4/common/src/main/java/org/vivecraft/mixin/client/blaze3d/RenderTargetMixin.java#L26
and it worked for me.

I'm not familiar with opengl and don't know how to do it in production-ready code and also on whose side the fix should be.
