 8.17.19  10:24 pm i don't know what exactly you're trying to do so this may not be helpful at all but things stop moving (at least on my laptop) when I scroll up past the newest entry?	 there's no way to stop new things from being added but scrolling up stops things from moving while you're trying to read them or whatever.
that's what it's supposed to do. on mine it stops almost, but new stuff still comes in. much less, but just enough to disrupt the reading experience every 2 seconds or so
