**System Information** Operating system: Windows-10-10.0.19043-SP0 64 Bits Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 431.07 **Blender Version** Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: `rBf1cca3055776` Worked: (newest version of Blender that worked as expected) **Short description of error** When using the Principled BSDF (transparency=1) or the Glass BSDF with Multiscatter GGX artifacts that look like seams are visible. These are definetly not refractive phenomena, as it does not occur with other microfacet distribution models. **Exact steps for others to reproduce the error** {F12933497} As can be seen in the test file, seamlike artifacts appear when roughness!=0. When changing the microfacet distribution model to a different one the artifacts are not visible.
