It's actually not as big a problem as I thought. It's just that on the 14" Chromebook, the upper portion of the red background gets pushed completely out of the frame - judging from the lower part, it's about three pixels in width, maybe four. The number *is* indeed readable, but on this screen, it appears tiny. It's no big deal, and most people wouldn't bother anyway. I have just found out how to make screenshots with the Chromebook, so I'll take one next time the opportunity presents itself.
