New design font has terrible for Greek
DINNextRoundedLTPro-Regular.woff (used as a font in the new design) has a kind of broken Greek subset. It contains only four glyphs (ΔΩμπ), but doesn't contain all the rest. So, words with μ or π are rendered in mixed font, these letters are much bolder than others, which looks terrible. Either remove these four miserable glyphs or add all Greek subset to the font file. Or better, use wider ranged font which contains all European writings (including Greek and Cyrillic, maybe also Hebrew, but probably not so critical like the first two). Most modern browsers support font subsetting via unicode-range, so font file won't be too big, especially in woff2.
There is a new redesign in the browser version of the site, not sure if it's rolled out to everyone or they're doing it in groups. But yes, those four letters are much bolder than the rest of the Greek letters:
Διαβάζω διαβάζω Ωραίο ωραίο μπαμπάς ΜΠΑΜΠΑΣ
Hopefully this screenshot shows how those letters are bolder than the rest:
edit: You can also see that μ and π don't line up height-wise with the other lowercase letters. I'm not a font guy so I don't know what that's called.
I'm having the same problem. Some letters look bolder than others and all the letter became definitely harder to read.

(Thank you also for this report)
Please give us some more information. As far as I know we do not have a new design. I've been working on the Greek course all morning and have not encountered any irregularities. Where did you see the errors. Could you get a screenshot s we can report this to the technical branch.
The type of writing, the police used, has changed. I understand that for some greek letters, some problem occured.
