Player armor is not rendering propetly when widget is placed in specific parts of the screen [Wynncraft]

[Rafii2198]

I have confirmed no other issue reports this bug

• I have searched for existing issues

I have confirmed the mod is installed on the proper side

• I have installed the mod properly

Current behavior

Depending on where the FER widget is placed, it causes armor to render differently. Likely due to Wynncraft RP.

It appears it only depends on vertical axis.

Expected behavior

Player armor should render normally no matter what

Steps to reproduce

1. Join Wynncraft with mods installed
2. Move the overlay that uses FER around

Minecraft version

1.21.11

Mod loader version

0.18.4

Mod version

0.5.4

Other mods

• Wynnic Enchantments Helper - my mod that implements FER
• Fancy Menu and its dependencies
• Wynntils

Stacktrace and logs

No response

Additional context

This is likely an issue exclusive to Wynncraft server as they maybe use some shader changes, they use a lot of tricks to make the server look really good, but this may cause this extremely weird interaction. Sadly due to the nature of my mod and FER itself I kinda can't really test it in other environment without creating a whole new mod.
Additionally, it's also not as black and white, for example they have cosmetic head pieces and the one I have renders just fine.

Oh wow, that is a weird glitch ahah
I'll be on it soon, thanks for reporting!

I made a bit of investigation, I managed to disable the server resourcepack while on Wynncraft and the issue disappeared, that means the issue is most likely caused by minecraft shader changes their resourcepack does

[Crystal-Spider]

Is it open source? Maybe I can check what their shader/resourcepack does and see where the incompatibility may arise

You would need a way to extract it, you can do that by using Server Unpacker mod or some python script. With the mod you simply need to join the server and it will automatically extract all of it.
