ok i had an old screen shot of a forum post taken 2 months ago, i have gone back to that post and taken another screen shot just now.

then i merged the old one, top part, and the new one, bottom part.

here you can clearly see the fonts have changed,
in the top (2 months ago) they are crisp.

in the bottom, they are not, and the spacing has changed too.
