While compulsively checking my question, I noticed that a mysterious in-site scrollbar appeared. When I click on the scrollbar, the question disappears and I have to reload! This leads me to believe that the scrollbar is evil. I'm pretty sure this isn't intended behavior, just curious as to why this could happen.
Click on the scrollbar:
Using Chrome on Windows 8.1.
Notice the first screenshot is on Meta and the second is on the normal site. It doesn't seem to be happening on Meta anymore but still happens on the normal site.
Asaf suggested I click on the "Inspect element" menu option. While I program, I don't make websites, so I'm not sure how to interpret what I've displayed. I'll post it here.
UPDATE: Now when I reload the evil scrollbar appears, then disappears, so reproducing the bug is probably going to be hard now.
