"If you are concerned about the appearance of a horizontal scrollbar in the new layout (like the one in your screenshot), you don't have to worry."

If I were concerned about a "horizontal scrollbar", I would have used the words "horizontal scrollbar" at some point.

We're talking about 1600px resolution, the screenshot was just to illustrate that last time they changed the layout, I had to take a screenshot of an actual monitor to get absolute proof that their quoted numbers weren't accurate in practice.

I regret bringing up an unrelated screenshot in an attempt to explain why someone with a 1600px screen needs to test this.
