The ratio of fonts isn't very good in 13.04. I mean when I open a webpage like Facebook which is(in my case) in both language of Persian & English, the font size is smaller for Persian than English, which annoys me. I didn't have this problem in 12.10. And I think the fonts looks worse in 13.04. I should mention I'm using Anki and for operating it well, I did this:
I don't know exactly, maybe this has affected my system. But I'd done this in 12.10 and my system fonts was OK. To clarify more I see these problem in my browsers(chromium & firfox much more). For example Goldendict is OK and nothing changed with it. Do you have any suggestion to back my system fonts to default?
