Notice the bottom border on the active tab (Windows 10, Firefox, Chrome, NOT mobile browsers, NOT Edge, though Edge has a similar issue).
Next one is strange. Notice the borders of the arrow from the first and second user. The bottom border of the second user is slightly thicker than the one above. Excuse me if this issue is already known, I haven't been keeping up with Xenforo of late.
