When you hover over "Questions" (in both main and meta) there is a tiny little yellow (or grey) line that shouldn't be there down the bottom, which irritates the graphical pedant in me. How to fix?
I'm not trying to be totally trivial here. I hope I learn more about how SEs are administrated from the inside by asking this question.
Image zoomed to double. Could be hard to see on certain monitors, but the green arrow is there to help!
