I agree that this is happening because the posts are loading. With a slow network, I can reproduce this just scrolling with trackpad/mouse wheel. (Would it help to post a demo video of that?)

This problem is occurring only when scrolling _up_ because when scrolling down, Discourse draws in a bunch of grey filler; when the posts become available, they pop in right where they’re supposed to be and the scroll doesn’t jank.
