What happened?

Whenever the player picks up an item, all moving Create contraptions teleport around the screen briefly before returning to their correct position. This only lasts as long as the animation of the item moving towards the player.
I have tested this with multiple shaders including Complementary and Complementary Reimagined, and they have the same issue. Turning off shaders altogether prevents it.

This might not be all that helpful since I have hundreds of mods running, but it shouldn't be hard to replicate this issue yourselves though.

Minecraft Version

Minecraft 1.19.2

Iris Version

iris-mc1.19.2-1.4.3.jar

Operating System

Windows 10

What is your GPU?

Nvidia GeForce RTX 2080 SUPER

Additional context

This issue does not appear to be fixed in iris 1.4.4 rc2, nor does the flywheel compat mod alpha.

Here's a video of it happening on 1.20.1. I am using Oculus 1.7.0, but I don't see why that would make a significant difference.

What kinds of logs/information would be helpful in identifying the underlying issue? I've got time on my hands so I can pretty much provide anything except a PR as I don't know graphics programming. :D

I am also experiencing this issue
Minecraft fabric 1.20.1
iris 1.7.2
Sodium 1.20.1-0.5.11
indiuim 1.0.34+mc1.20.1
Create Fabric 0.5.1-f-build.1417

Perhaps we can narrow the scope by testing several combinations of:

• Minecraft version
• Create version
• Shader version
• Iris version
• Sodium version
• OS type
• Hardware (probably just GPU vendor but who knows?)
