[Shaders] Still struggling with "X-Ray" Bug/Glitch

[hunarii]

• [ SUMMARY ] ive found a handful of people who reported this issue and easily fixed it by turning "Fast Render" off. When I turn off "Fast Render" it gets rid of only half the issue. Some items disappear and are no longer visible through walls, while some items stay visible through walls. The issue persists no matter what kind of shaders I am using. From what I've found this is also a really old issue, dating back around 3-5 years, with some commenters saying the issue will be fixed in newer OptiFine versions. Haven't really seen anyone having this issue now, only me.

• [ HOW TO RECREATE ISSUE ] Use ANY shaders with OptiFine HD U I6.

• [ WHAT I AM USING ] I am using "OptiFine HD U I6" for 1.20.1 on 1.20.1. I am using around 60+ other mods within my modpack. I have OptiFine downloaded on my installer however I am using Forge for my modpack and have OptiFine in the mods folder as well. I am using Forge version 47.3.0 for 1.20.1.

Here is my full list of mods: https://pastebin.com/dW3UMCRA

• [ DEBUG SCREENSHOT ] Here are 2 screenshots of my bug, one with "Fast Render" on and one with "Fast Render" off:

[ WITH FAST RENDER ]

[ WITHOUT FAST RENDER ]

[ DEBUG DESCRIPTION ] It is a bit difficult to see do to my shaders being so dark, but in the "WITHOUT FAST RENDER" screenshot there are items such as chests, beds, and signs visible through walls. In the "WITH FAST RENDER" screenshot, there are items such as beds, blocks that emit light, modded mobs and modded blocks.
