I have a problem with strange depth of field artifacts in Eevee on my Mac Pro (tech specs on the pictures below). It looks like everything is what it should be. defocused is cliped by the camera (but its not the case of wrong camera parameters). Render is transparent in this areas. Sometimes even if the viewport shows me the proper Depth of Field, the render has still the same issue.
Thanks for any help!
