Short description of error
Hello, after updating to Ventura (the latest Mac os) which has Metal 3
the following bug is occurring with blender 3.3.1:

When Subsurface Scattering on a Material is used while a Volumetric Material is also active in the scene, the subsurface scattering appears darker.

The problem is visible on the render results too. Not only in the viewport.

The problem appeared only with Ventura, not with the previous version of mac os

Exact steps for others to reproduce the error

Download the file on a M1 machine with which is running Ventura
Set in Render view
Activate the "Volume" object while on render view
subsurface scatter should get dark

Hi, thanks for the report. I'm not able to reproduce this. Perhaps mac/M1 specific.
@ThomasDinges, can you check?

Hello @PratikPB2123 thanks for the comment.
I jus downloaded the release candidate 3.3.2 and the problem is resolved there. So I guess the problem will be solved when 3.3.2 will be officially released.

thanks again.
