Why the gradient effect with Interactive fill tool is so bad?

Obvious appearing scales.

This is what I am talking about:

  • Is that on-screen or an exported image?

    In any case, here is a screen shot more or less replicating your gradient, from inside CD. Your image is the right half.

    and the exported PNG:

     

    If your image is inside of CD, it may well come down to the video driver. If your image is an exported image, can you provide a sample file?

     

    • Hello and thnx for assisting.

      Yes it is exported, but you can see this on the screen too.

      Is this problem everywhere, as I see yours has too but of course much better than mine?

      • Gradients have historically caused display issues depending upon the monitor's drivers. Some are worse than others...and of course, it's hard to see someone's monitor from here.

        But, as this is your export, it isn't just about the monitor as the banding is apparent in the export. Which is one reason why a sample file would be good. Often times setting intermediate stops can help, but most gradients that look good on-screen and print will have the bitmap edited in a photo editor and a diffuse filter, etc., applied to it.
