Path Tracing Blurry

Hi everyone
I did my first test rendering with the Path Tracer here and I have a problem with the windows.

The Windows


have some sort of blurring artifact that is only visible in a few places, the rest of the discs appear to be good and sharp.

Does anyone of you know the problem or a solution to this?

Thank you very much

Open the Glass Material and go to the details panel

Translucency > Advanced > Translucency Pass > Set to “Before DOF”

Thanks, great it works
