Need help to remove banding

[Polychromika]

Hey everyone,
I’m using the app for some time now and I always have problems to remove banding in my images. As soon as I use a gradient or airbrush it creates banding. The tutorials I watched said to switch to 16 bit but as I understand it that’s not possible with the app.
Can anyone help me with this please?

Artstudio uses 16-bit quality when painting, but layers are stored in 8-bit.
So to prevent banding issue it is always better to paint a long stroke instead of multiple small strokes.

Gradient - make sure the "Dither" option is enabled, it should improve banding a bit.
