System Information
Operating system: Fedora 39
Graphics card: NVidia GeForce 2060 RTX SUPER

Blender Version
Broken: 4.0.2
Worked: Unknown

Short description of error
The antisotropic property of the Principled BSDF shader does nothing, even in Cycles.

Exact steps for others to reproduce the error

Set render engine to Cycles.
Set viewport mode to full render.
On the Principled BSDF node of the cube's Material, change metallic to 1, and roughness to 0.1.
Start moving the Antisotropic slider around.

The material will not change, even with different geometry. The slider has no effect at all.

I am also not able to reproduce. Ensure that you're render engine is set to Cycles since Anisotropic is only available there. Can you provide a better set of reproduction steps?

Must be an issue with my system, or the snap. I’ll try the AppImage and Windows.

Drat, IDK how I forgot to set it to Cycles. Well, that narrows down the problem a bit I guess. I am having it with a different file, but that's not a bug now afaik.
