User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130104151925 Steps to reproduce: Font rendering is unpleasantly changed (broken?) in version 18. It appears not in all websites, not in all fonts, even not in all places of same page. Initially page may be displayed as usually, but just after scrolling, text becomes blurry. Refreshing page with F5 key returns back to usual rendering. Tuning hardware acceleration and other options has no effect.
Created attachment 699692 [details] Example of rendering text after scrolling of page If you zoom in, you can see what Cleartype is turned off and antialiasing becomes grayscale.
Could you provide an example (URL, html file), please?

This particular snapshot was taken at http://habrahabr.ru/post/165123/ (Strangely, if I save this page with ScrapBook+ add-on, it then rendered normally) Also multiple people reporting same rendering on GMail pages.
Yes, bug 828206 is about the same. Maybe it caused by some rules in CSS stylesheets of these sites, but not sure which one exactly.
In bug 828206, a user says it's fixed in FF20/21. Could you confirm with Nightly FF21, please? http://nightly.mozilla.org/
Confirmed, fixed in Nightly 21.0a1 (2013-01-09)
