314L+ Banding on images

[Robfal]

I have a 314L+ camera which has worked faultlessly for years however I now seem t have a problem when stacking frames in DSS.  (Oddly I don't get a problem when stacking in ASTAP or Maxim, I think! so this might be a stacker issue)

I have dark horizontal bands across the stacked image (often in line with stars).  Picture is an overstretched example but does clearly show the problem.  I am using INDI and Ekos as the camera software.

What INDI driver should I be using ( just using a standards Astroberry install)?


I know this might be a stacker issue but not finding any answer anywhere so any help appreciated
