Blurry Textures 1.21.5
Hi, when playing in 1.21.5, I am getting blurry textures and mobs. Not having this issue in 1.21.1, or when the shader is off so I'm assuming its related to the shader? is it possible my computer is just having issues? Obviously its a very new version so I'm not expecting everything to be perfect right away but if I could get some help that would be great! Thanks

Low FPS but I have a decent rig
I have had problems with my FPS for a very long time, I fixed it a while ago and it randomly plummeted again I get around 50 FPS with complementary shaders with around 100ish mods alot of them are optimization mods and other quality of life mods nothing major (I dont think). If anyone could give me tips or help me out that would be amazing. One thing that is kind of weird is Sodium actually lowered my FPS for some reason, I get 200 fps with no shaders and I got more without Sodium.

Mixin transformation of net.irisshaders.iris.pipeline.programs.SodiumShader failed
whenever i try to use a shader it crashes
Hi ! first of all sorry for my english, it's not my first language. I'm also a new player on MC so i may struggle with explanations and giving docs lol. So i'm playing on the new version (1.21.5) and every time i try to put a shader (Vibrant or complementary) my game crashes like 1-2 seconds after the loading page in game. But when i don't have any shaders on, it doesn't (but the game's ugly...). I'm playing with mods (fabric, fabric api, fabric language kotlin, sodium fabric, iris fabric, and m...

OpenGL error spam in Iris 1.8.8 for 1.21.1
I'm pretty sure this wasn't the case for 1.7.5.
Shaders I tried are the lastest in-dev versions of Bliss, Photon and Photon GAMS, all having the same issue....
Solution:
Issue narrowed down to Distant Horizons version 2.3.0-b. Try their nightly build and see if that issue been fixed.
