Expected Behavior

The sky shouldn't be moving.

Actual Behavior

The entire sky rotates based on the player's direction... in a dedicated server environment.

Steps to Reproduce

1. Load a world onto a dedicated server environment
2. Have another player carry a Wandering Trader holding a potion or Priest from Iron's Spells and Spellbooks
3. Have the player carrying the Wandering Trader rotate themselves and observe the clouds rotate around said player and feel the sudden significant drop in FPS.

Screenshots encouraged

I think a video would explain this better: Discord CDN link

this also happens in singleplayer with allay's holding enchanted tools, causes the particles to go whack

It also destroys FPS whilst it happens

This happens on a 1.19.2 multiplayer server with the Duckling mod when picking up a duck.

Do you have optifine?

Do you have optifine?

I did not use optifine but sodium may have been installed at the time. I did not have shaders or anything else. Everyone on the multiplayer server experiences the clouds moving when this bug happens even if it's only one player who triggers it.

OptiFine was not installed at the time of occurrence in the video attachment

The sky starting to spin seems like an issue with your shader

I hope it's not a weird interaction with Create's Flywheel since there are no mods that add shaders to my knowledge in the modpack
