Shiny band

Does anyone know what happened here? I’ve seen this issue happen when the printer changes speed.

But I’ve slowed down my speeds a little to prevent this from happening.

Been printing with the same speeds for over a year on my x1c
and never had this issue. In the preview I can see where the issue happens under layer time.

All the other options it shows one solid color, What’s happening?

Based on the little preview, I would suspect the layer time is being extended due to the color swaps. Is this affecting your adhesion or finish?

Yes it affected the final print but no adhesion problem
