Worked: (optional)

Short description of error
DOF in EEVEE Render doesn't render correctly, there is a "cut-off" like, from focused part, then blurred part. (not gradual blur)

Exact steps for others to reproduce the error
Render the scene as-is, and you can notice on the cyan-lights the cut-off, then you can see on the back of server there is cut-off too!
