GUI Rendering issue in Wynncraft

[EnderNon]

Wynncraft uses a resource pack and font + shader fuckery to render their guis. 20% of the time when starting wynncraft the on screen font gui thing is broken and the other 80% of the time it works fine.

How it should be

In broken state: Festivaal of Bonfire display in top left is gone, right side panel shifted to bottom middle, top right server display is gone

Screenshot reproduced with absolutely no mods other than IF enabled:

Found on Archlinux, prism launcher, Minecraft 1.21.4, IF version 1.8.1+1.21.4, Fabric 0.16.10.

When loading into Wynncraft, 20% of the time it is broken, 80% of the time it is not. But then F3+T seems to toggle the broken or not broken state.

Upload the game log. Also how can I get to that GUI? Do I only have to join or do certain other steps? I need a list of steps to reproduce the issue

To get to this gui, join "play.wynncraft.com". Should spit you into this class selection screen after installing resource pack. I don't know if the right side panel appears if you have no save data (I do not have an alt to test this on) but the other displays should be there I think
