Jittery, Jumpy, Distracting movement.
I have autocomplete configured to the default mode where it remains in one location as you type. However, the autocomplete window does not remain in its correct location as results are populated, and what's worse is that it momentarily jumps around which is quite distracting. I've made a gif to illustrate - note the quick jitter at the end. The autocomplete is a very important part of an IDE experience, and is central to the impression that Atom leaves. Fixing this small issue would make Atom feel much more solid.

@jordwalke I'm unable to reproduce this. Is it still a problem for you? If so, could you provide some reproduction steps?
Yes, it is still a problem for me. Any time I simply use autocomplete (I happen to be using Merlin/ocaml). The repro steps would involve setting up a merlin setup. Not sure if you're game for that.
