Changing Movie Scraper renders poster art in low quality?

My Vero V has been around for awhile and I guess it was still set to use the older TMDB scraper. I noticed that it wasn’t scraping new files and saw the add-on is broken and so I changed to the Python version for my media directories and it re-scraped evertyhing.

However, all the poster art and thumbnails are in some kind of low-rez mode? They kind of look like ‘comic book art’ or like they are only using 8bit color? I have my GUI set to 1080p and this was not an issue before scraping. If I set the GUI to 2160p, they render correctly. So the thumbnails appear to be ok, but something is happening now in the 1080p rendering of the posters?

I’m using the Estuary skin. Anyone have suggestions on what could be going wrong here?
