System Information
Operating system: Windows 10/11
Graphics card: GTX 1080 / RTX 3060

Blender Version
Broken: Persisting from 2.8 to the 3.0

Short description of error
Baking textures creates artifacts.

Exact steps for others to reproduce the error
Nodes: texture coordinate -> object output to musgrave texture, plug that into principled bsdf and bake.
Textures is baked in 1024x1024 but increasing resolution as far as 4k still produces noise.

In provided file I tried to have uv island in similar size as what they would be on image provided above.BakeBug.blend
Issue also exists even if I scale island in file above to take up whole available width.

In #81710#1249339, @brecht wrote:
It's a problem with long thin triangles, the workaround is to add a few loopcuts.

So this is a duplicate of #81710 (Artifacts appear in texture bakes [stripe pattern]), will merge these reports

This looks very similar to a previous problem: #81710

Using the workaround from that bug, if you add more loopcuts to create more even geometry and reduce long faces, the lines go away. Will mark as a duplicate for now.
