Clicking through your messages, the difference looks always the same (unless the image was copied). Do I understand correctly and does it fit your observations so far that if there is an irreproducibility, it has only two outcomes, i.e. the observed diff and the reference?

I believe we have so far saw the difference twice (cms-sw/cms-bot#1456 (comment) and #32622 (comment)), and indeed the difference looks the same in both (the images were not copied between the two PRs). It could be that there are only two possible outcomes, but with so few occurrences it is hard to say.
