Disabling mixin.perf.faster_texture_loading in the ModernFix config should fix it for now; I will make the mod do this automatically in the next release.

Sounds good, probably related to how the mod mixes textures together on startup (applying latex to a block changes its texture).

Latest release includes this change.
