System Information
Operating system: KDE Neon - Linux-5.13.0-44-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce GT 1030/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 510.73.05

Blender Version
Broken: version: 3.2.0 Release Candidate, branch: master, commit date: 2022-06-06 16:10, hash: 128aa7f3b0
Worked: Blender 3.1.2

Short description of error
Masks don't work like in Blender 3.1 when applying on displacement

Exact steps for others to reproduce the error
Open the Blender file that I put here as an example, open it in version 3.1 and also in version 3.2 to notice the mentioned differences that occur in the mask because of some difference that exists in the way displacement/normals works (maybe)

Screenshots and example file:

Normal Bug.blend

[Based on the default startup or an attached .blend file (as simple as possible)]

Changed status from 'Needs Triage' to: 'Needs Developer To Reproduce'

I can replicate that. It seem normals now take displacement into account in 3.2, so that might be an expected change in behavior. Tagging the module for more information.

Omar Emara changed title from ~~Problems with masks and displacement~~ to EEVEE shading normals are affected by displacement in 3.2

Ok, if Blender is working correctly then I'll make changes to the material group to correct the distortion of the mask (turning off displacement and using the bump node in the diffuse node)
