Hi @joramatang ,
Thank you for your patience while we checked with the product team.
We've confirmed that the Dither option is currently not supported for Freeform Gradients in Illustrator. While dithering is available for Linear and Radial gradients, it is not implemented for Freeform Gradients at this time. So what you're seeing is an expected limitation rather than a bug.
If dithering support in Freeform Gradients would be valuable to your workflow, we encourage you to submit a feature request on our Illustrator feedback portal, as suggestions there are reviewed by the product team for future enhancements:

Thanks again for bringing this up and helping us improve Illustrator.
Regards,
Abhishek
