Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.78 Safari/537.36 Example URL: https://accounts.google.com/ Steps to reproduce the problem: 1. visit https://accounts.google.com/ 2. the 'Sign in' and 'Continue to Gmail' are disgusting 3. open Mozilla Firefox an marvel at stability What is the expected behavior? h1 and p tags should be rendered more beautifully What went wrong? Updating to latest Chrome version. Screenshots from: google sign-in feedspot google hangouts Does it occur on multiple sites: Yes Is it a problem with a plugin? N/A Did this work before? Yes 59.0.3071 Does this work in other browsers? Yes Chrome version: 60.0.3112.78 Channel: stable OS Version: Linux Mint Sonya 18.2 Flash Version: Shockwave Flash 26.0 r0 This happens in Google Chrome, haven't tested it in Chromium (I'm lazy after work hours and it's already past my bedtime). This issue happens also on https://hangouts.google.com/ in the chat history on the author/time notice. Also on feedspot.com. Maybe connected to https://bugs.chromium.org/p/chromium/issues/detail?id=744247

Thanks for the report and sorry for the trouble. I can't reproduce on my Linux system, presumably there is something unusual about your setup. Over to Blink>Fonts triage, hopefully they will have some suggestion to figure out what's special about your setup. Worst case if you're willing/able to do a bisect between chrome 59 and chrome 60 that should give us a pretty good idea of what change might have caused this: https://www.chromium.org/developers/bisect-builds-py

I have the same problem probably. It seems that Chrome 60 does not anymore respect hinting settings for not antialiased fonts from fontconfig (~/.fonts.conf). Chrome: Version 60.0.3112.78 (Official Build) (64-bit) OS: Ubuntu 17.04
