So I pointed my hosted instance to feddit.org and so far haven't encountered the issue (though I am browsing as a guest). I see feddit also runs Tesseract, but it shouldn't make a difference which one I test with since they're the same version.
Additional questions to the ones in the first comment:
What browser are you using?
What platform (iOS, Android, Mac, Linux, Windows, etc)
You mentioned it seems more apparent in media heavy feeds. Can you elaborate on that? Images? YouTube and other embeds, etc?
What sort order? When I was testing, it was by "new" which may or may not trigger the crosspost issue as often as other sort methods

Linux

Maybe that was a bit misleading because I set previews to always show. I do believe it has something to do with media expanding though.
Here's the settings section

I just had a jump on the feddit.org "all" feed with "scaled" in "hybrid" mode. It happened later down though, where only unread posts were shown.
It skipped exactly 20 posts. Not a single skipped post had a crosspost. Also the last seen posts before the jump have no crossposts.
