System Information
Operating system: Win 10
Graphics card: 980 Ti

Blender Version
Broken: 3.1 beta & 3.2 alpha
Worked: 3.0.1

Caused by 74afc86d4b

Baking to vertex colors (for example ambient occlusion) seems to be completely broken since 3.1 beta, as it is producing randomly looking artifacts, nowhere near to expected results.
The same scene & baking / rendering settings works better in 3.0.1 (with smaller bugs).

When rendering to texture, the same setup works correctly even in 3.1 beta & 3.2 alpha.

Exact steps for others to reproduce the error
Open the attached .blend file in 3.0.1 and 3.1 beta / 3.2 alpha, hit Bake and compare results.

@jakasan2000 hi, please don't claim any task unless you are planning to fix them :)

Thank you guys for confirming the problem, I just hope somebody will be able to fix this without reverting that "ray offsetting" commit, because it fixes another issue I am facing when baking to vcols (black artifacts when mesh is far from 0). Thank you again!
