Haloing problem

[Andreselos]

Hello guys, I have a problem to remove this artifact that I believe is halo, correct? I tried in every way all possible combinations, Alpha_dehalo, FineDeHalo etc.. and nothing works, at most it's a small decrease, has anyone gone through this and have a solution?
Thanks.
