While stacking live pictures in Infinity with a new Horizon mono, I am seeing a "window screen" and/or mosaic pattern. This effect persists in both FIT and JPEG files once they are saved. Please see attached a screenshot. In the first sub, everything seems OK, but in the second sub, as they stack, the problem emerges. Stacking more items together does not help. Infinity parameters such as subexposure durations, offsets, and binning ratios did not assist, while 2x2 binning sometimes did.
