Bug with The Outer Worlds Lossless Screenshots

Noticed when taking screenshots of The Outer Worlds the lossless PNGs generated by SpecialK are a photo-negative of what was in-game. afaik, this is only an issue with this game. See attached img. (reposted here as I accidentally posted in the wrong section)

edit: If it helps, I have texture caching off as per PCGW’s recommendation.
