As soon as I open the astral tome, my GUI changes to this:

My Modlist:
Adventure Bags
Akashic Tome & Morph-O-Tool (I've tested using this and not using it, neither fix it)
Astral Sorcery
Psi
Quark
Botania
ChickenChunks
Embers
Tomb Many Graves
Mouse Tweaks
Inventory Tweaks
JEI
Vanilla Magic

This is fixed by re-loading resource packs

Disable optifine's fastrender.

Or they're is something else fiddling with shaders/gui.

Ah, okay. That fixed it, thanks :P
Forgot to list optifine in my list of mods, too
