Strange artifacts (probably due to Adaptive Lights)

I’ve a strange problem in the last 2 projects I’m doing.

I’m sure that is not an overlap faces matter.

I’ve tried to investigate enabling all the render channels and my attention fallen into VrayShadows channel.

Looking to those squared artifacts, I’ve tried to disable the Adaptive Lights option and, checking the VrayShadow channel, it seems that is the reason..

Here the PSD file with some tests

Is it good to have those square with Adaptive Lights ON?

If it’s fine, what do you suggest to check what’s going on?
