828241 - Somewhat blurry fonts in Firefox 18

Status: RESOLVED DUPLICATE of bug 828206

(Core :: Graphics: Text, defect)

Description

[Roman Dawydkin]

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.

If you zoom in, you can see what Cleartype is turned off and antialiasing becomes grayscale.

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.
