Please describe your issue in as much detail as possible:

Sometime during the last few hours, the font changed for the steam browser which has caused several issues when it comes to kerning. Have a look at http://pix.toile-libre.org/upload/original/1489858237.png
The amount of kerning between two f's is just unacceptable. The same issue applies for two v's, which becomes almost indistinguishable from w.
Another issue this recent change seems to have added, is lack of spacing between elements, which can be seen in the steam settings window for Steam in-home streaming http://pix.toile-libre.org/upload/original/1489861673.png

This issue didn't appear with a steam client update, seeing it went from working fine to being broken without restarting the client.

Steps for reproducing this issue:

1. Open up the steam browser
2. Go to any community page
3. Look for a reply with a word such as "offer", or write ff in the reply-field
