Before reporting, I have confirmed that

• This bug does not appear to be reported on GitHub Issues before.
• This bug still exists in the latest version of the Minecraft Transit Railway mod.
• I have tested this in the official version of Minecraft Transit Railway, not a modified, custom, or unofficial build.

Describe the Bug

Trying to use MTR mod with shaders, when I do, this strange shape appears over the screen that definitely has been textured like an MTR block. It doesn't go away in any view (1st or both 3rd person). On top of this, when the shaders are enabled, none of the rails render. When you use the brush, you can see the colour fill of where the rails should be, but there are no actually rendered rails in that location. I've tried with the kappa shaders that were used in the online video demo from Jonathan Ho, and I've tried with my own shader choice (chocapic) but the issues remain consistent through both of them.

The strange object across the screen and the colour fill where rails should be can be seen below.

Reproduction Steps

1. Load forge 1.20.1 with the following mods

2. Enter game and select shader pack
3. The problem then arises, but goes away when shaders are disabled.
