I get a warning when this is about to happen to me: the feed moves itself up and down a couple of pixels repeatedly, little a little jiggle. It reminds me of when you are looking at a web page and elements are still loading and they are changing the layout as they load. Usually lasts a couple seconds and then refreshes the feed on its own.

It only happens after I scroll. Is there like a scroll-momentum variable getting set incorrectly or something?
