Topaz Photo AI struggles to enhance digital images that have been scanned from 1960/1970s photographs printed on honeycomb (hexagonal) texture paper. In some cases the software enhances the hexagonal pattern making the “enhanced” image worse than the original. The human eye can clearly discern what the enhanced image should look like, so should an “AI” algorithm; at least the hexagonal pattern should be detected and removed.
Someone (compupix?) reported a similar problem in November 2022. You might consider giving each feedback message an unique ID number that can be used for future reference.
