So very wide but not very tall? What is the actual window size in pixels?

I can reproduce in Firefox with a 1280x720 browser window, on meta, by picking Laptop in “Responsive Design Mode”, scrolling around, and noticing the scrollbar at the bottom appear and disappear as I do so. I notice that the scrollbar appears when I pass the bottom of the post stream, and does not appear while I’m in the middle of the post stream.

I can also reproduce in Chrome - from my testing - `$(window).width()` is 1000, `$(window).height()` is 540.
When scrolling past the last topic, the horizontal scrollbar appears and `$(window).height()` becomes 523. There is a “sweet spot” when the jumping occurs in which the horizontal scroll appears and disappears without user interaction in between the last topic and past the topic.

I had reported this a little while back. Sounds like it might get looked into at some point:

Here’s another weird thing that can happen because of it: [https://streamable.com/7y8pc](https://streamable.com/7y8pc) With that said, this is a minor thing that the majority of users probably won’t encounter.

I’ll add that I’m using a Laptop with a 15" screen, resolution is 1366 x 768
Not only does the screen jump around, a scrollbar appears when you move past the last post

Yep, also mentioned in my report 🙂 That’s the core of the problem. It looks like I can reproduce it up to about 1475px width. Once the composer “detaches” from the sides of the browser window, it goes away.

This works perfectly..
```plaintext
#topic-progress-wrapper.docked {
right: 19vw;
margin-right: 1px; <<< This works..
}
```

Maybe @awesomerobot can take a look when he has time.
