Everytime I open the guide book, my GUI gets this strange rendering bug that seems to be turning it into the liquid starlight texture, I tried removing all mods except Astral Sorcery yet it still persists, I've heard this is a known bug, just wanting to bring it up since it's still present as of 1.8.10

and I should mention that I am not using Optifine

When it happens with only Astral Sorcery installed, what else is running? QoL mods? Shaders? Forge version? Can I get a screenshot of your mods directory?

It's minimalistic at best, mostly focused on mods about night which is why it bums me that AS isn't working properly, if required I can get a log, no shaders or resource packs, Forge version is 14.23.3.2680

Here is a simple log of me loading into a test world, opening the guide to cause the bug, then closing:
latest.log

It may also be chalked up to my hardware, that's what I might settle on if there is no software-based fix.

Vampirism has a shader with a known conflict: #689

Try enabling the 'weakSkyRender' config option in the AS config, that's about as far as supportability can go for that one on our end.

Unfortunately this did not work, oh well, I can remember how to do Astral Sorcery decently without a guide, I can live without opening it, thank you for helping, Doomgull.
