Attachment: 2017_bad.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170918122929

Steps to reproduce:

I have installed firefox 55 ( and also 56 ), I use archlinux 64 bits


Actual results:

on some sites with some fonts I notice that the numbers can be badly misaligned, for example in the string "2017" the number "1" can be misaligned,

example of bad rendering for this website :

Expected results:

the numbers should be correctly aligned,

with firefox 54 and previous versions I didn't have this problem, I suspect this patch added to firefox 55 in order to correct a problem related to freetype2 :

finally it's not a bug from firefox,

the problem comes from the font "nimbus sans regular", firefox selects this font, but chromium uses another font, which gives this difference about the rendering
