By googling for "Chrome font looks weird", I've found that page here:
http://www.neatorama.com/2014/09/05/...How-To-Fix-It/
As far as I understood, there was a recent update which caused that. Don't know any details, don't ask me if that has any drawbacks - tech is definitely not one of my strengths
Just found that site though and it worked for me.
