System Information
Operating system: Linux-6.2.0-32-generic-x86_64-with-glibc2.37 64 Bits, X11 UI
Graphics card: NVIDIA GeForce RTX 3070 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 535.86.05

Blender Version
Broken: version: 3.6.2, branch: blender-v3.6-release, commit date: 2023-08-16 16:43, hash: e53e55951e7a
Worked: (newest version of Blender that worked as expected)

Short description of error
Inconsistent behavior when rendering double faces.

open the attached file and switch between optix and cuda and CPU hit f12 to see the difference.
even if I cant coma up with a situation other than when, by mistake, have copys of the same object on the same place or bad luck with intersecting objects I think it's worth to repoort it. all our computers are using optix and i didn´t notice anything untill I sent work away on a render farm witch obviously used cuda.

Sounds like #96475, will check previous versions to see if this has been ever resolved

No previous version after 3.0 worked, so this is limitation of current system as described in report mentioned above, so will close this report.
