Is it a mod compatibility issue?

Yes

Minecraft version

1.19.4

Describe the issue

As the warning in game said - I have probably found some kind of incompatibility between Immersive Portals and my other mods.

The issue is that the dropped items do not render/appear. I can pick them up, but they do not show up on the ground.

Here's the full log: https://mclo.gs/mZgV0ub

Disabling Immersive Portals fixes the issue

Hm, yeah - Disabling Iris causes the issue not to show up
I'm using AstraLex shaders.

Let me know if there is anything I can do to help you debug this

Does this issue occur without Iris?

Maybe related to this #1332
