On browser windows of certain widths, when you scroll down to the bottom of the page under the post stream, the horizontal scroll bar appears. I believe this is a regression.
The best thing is, when you’re on the threshold of the bar appearing, the scroll bar ‘humps’ the bottom of the screen.
Here’s a video of exactly what I mean, on [meta.discourse.org](http://meta.discourse.org). Though I identified it first on our own discourse instance.

This is happening with Chrome on Ubuntu, with a window width of approximately 960 (i.e. half of 1920), I can identify a couple of (separate) width ranges where it happens: around 935-975 pixels, and 855-880 pixels. There are also ranges where the scrollbar appears but without the amusing oscillation.

Ok, which DOM element is exceeding the browser width at these specific sizes?

This was actually a fairly huge issue, at those width stuff like back and forward navigation plays up.
Fixed now per:
