Weighted normal artifact

Udjani

I was traying to use custom normals in some faces to reduce the gradients without having to use hard edges, but im getting some artifacts when using it, things look fine without the custom normals. 

So is that just how it is?, did a bake test in painter too, also doesn't work but the problem there is different.
