What are these lines/bands?

Hi guys, I get these lines/bands in my images with the QHY9. Any ideas on what it could be? They show up in the final image, and are a bit annoying….

They appear in luminous frames, and dark frames, not in the Bias. If you zoom in it appears that there is some sort of pattern below the band, like a checkerboard? And the smaller section above the band looks clean?

I don't think it is an issue with the USB cables, because I'm using the same cables with the OSC with no problems. I will double check though.
