Hi everyone!
This is my first post in the forum. I hope doing things well and be able to contribute and learn a lot 
I’m dealing with BI and DOF. My node setup (attached in this message) is very simple, so I think so I guess my problem is easy to fix.
I get some strange lines in the lightest areas, as you can see in the attached image. I don’t understand why they appear, because the DOF effect should create a soft blur contour.
Any idea?
