Pixels instead of shadow on layer style

[Мирон27315464ktjs]

Have such an issue (attachments), didn't find any solutions for it

Istead of creating nice shadow it looks like mess of pixels

I can't understand Russian language but you can:
- First make sure the the Blending mode is not "Dissolve".
- Reduce noise to be "0".

If it doesn't work,
Change the contour to be Sharp line:

     ... Double click it and you can edit or choose "Linear" from "Presets"
