Several of the Iron's Spells & Spellbooks (https://legacy.curseforge.com/minecraft/mc-mods/irons-spells-n-spellbooks) transparent hud elements become fully opaque when using immediately fast

Spell Bar Overlay

Steps to reproduce:

With ImmediatelyFast: (both items have the same spells equipped)

Steps to reproduce:

1. Obtain a spellbook with spells
2. Cast a spell

What it's supposed to look like:

I should add, after looking at the hud code, it hasn't been optimized since the direct port from 1.19. i'd appreciate more information on the issue as i'm no rendering expert and i don't know what immediately fast does behind the scenes.

Also, when ImmediatelyFast is installed when using Iron's Spells this also happens:

We have a couple people a day show up in our discord with this and our only option at the moment is to tell them to remove ImmediatelyFast. If there is something on our end we can do let's discuss

You can hit up Smalls or Iron in the discord https://discord.gg/4gDYuJtK

Try disabling hud_batching in the config file and check if that fixes it for now

Looks like that resolves the heartstop issue.

Can confirm immediatelyfast version above 1.2.13 also fixed this
