No, this is the news feed I've been having problems with, and for over a month now: when you filters posts by most recent, you'll get maybe a couple of recent posts, then it'll skip ahead to a few posts from 2 hours ago, then skip ahead to a few posts from 7 hours ago, then skip ahead to a few posts from 21 hours ago, then skip ahead to a few posts from the day before, then start skipping back to posts from 2 hours ago. And sometimes, if you hit refresh, then some posts will disappear while others that didn't show up before suddenly appear.
