Weird light lines in rendering

Hi guys,
I have this problem in EEVEE, with the depth of field.
I get these weird line strikes and I don’t know how to make
them go away. They don’t appear in viewport.

I’ve tried changing the focal length and the F-Stop, the objects scale and
can’t figure it out.

The camera focus is set on a plane (wireframe, red color), with a particle system
(blue color). materials are all emission.

Please help me get rid of those lines.
