Does anyone else notice a change in the font used in diffs (It looks "thinner"), or is that just a side effect of me clearing my browser settings?

edit: Just me, idkwtf is going on. Apparently my Arial font is corrupt or something.

edit 2015‎-07-06: Incidentally, this issue went away when I next updated my browser.
