After update of nightly build from 02 to 03 June majority of HTML pages is, with hardware rendering via D2D on Windows 7, broken down to not usable level. Whole boxes/blocks are missing, mouse over over them occasionally help (but not always) and content is appearing, although many times distorted. Apparently bad addressing. Turning HW acceleration off solves the problem. I consider this issue very serious. Curiously, SVG documents are not affected, but only some HTML web sites, like  google.com and amazon.com , for example...

Reproducible: Always

Steps to Reproduce:
1. open www.google.com


Actual Results:  
Only logo is visible and blinking cursor, rest of the page is not rendered properly (see the attachment)

Expected Results:  
You should see logo, input form and couple of texts and links

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0a1) Gecko/20110606 Firefox/7.0a1

latest OK:

Switching to fresh/empty profile is not helping either...

HW accelerated DX9 rendering/composition on WindowsXP is all right as well... (another GPU and another driver version, but still NVidia's latest)

This is happening because you have disabled font smoothing in your Windows settings, and bug 661471 caused text rendering to break in this case. Bug 662115 describes this issue further.
