[Sunflux]

Not that specific sample file, but the same scene. I have my own rip of this movie, and I see the exact same banding with it (it's a problem with the original Blu-ray)... however, I tried enabling dithering, took a screenshot, disabled dithering, took another screenshot, and I see no difference between the two. At all. No smoothing or even noise for that matter.

At any rate - Kodi is not doing anything wrong here. The banding is in the source.
