Noise when rendering images with out of focus objects

**D5 Render Version:**2.4
**Graphics Card:**RTX 2080 TI 12 GB RAM
**Driver Version:**Studio Driver 531.41
Issue Description: When rendering images with out of focus objects, there’s a lot of noise and refractions around the blured areas. I tried different resolutions - and the noise amount changes, but it never disapears. Is there a way to reduce this noise? Thanks a lot for any hints.
