New issue 140678 by ayubad...@ayub.info: Poor / jagged font rendering on
Windows
http://code.google.com/p/chromium/issues/detail?id=140678

Chrome Version : 21.0.1180.60
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)

URLs:
http://google.com/search?q=fonts+in+chrome+look+bad

Other browsers tested:
Firefox 4.x: OK
IE 7/8/9: OK

What steps will reproduce the problem?
1. Viewing webpage. It seems native (installed) fonts render a little bit
better than @font-face, but they are still faulty.

What is the expected result?
Clear, smooth fonts that are pleasant to look at.

What happens instead?
Jagged fonts that make webpages appear unpleasant. Loss of user loyalty and
browser switching.

Please provide any additional information below. Attach a screenshot if
possible.

Issue has been tried with Microsoft ClearType on and off, with the latter
option only making things worse. Issue affects two independent computers
when on Windows 7, however it is not apparent when browsing with Chromium
on Linux. Others on various websites claim issue is persistent in Windows 8
Consumer Preview.

An effort should be make to produce a custom font rendering engine as
Firefox and IE do, rather than rely on the unreliable OS.

UserAgentString: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1

Comment #6 on issue 140678 by tre...@voodoocreative.com.au: Poor / jagged
After experimenting with this issue I've found that setting the font-size
larger than 49px seems to enable nice anti-aliasing.

I know that Firefox uses "text-rendering:optimizeLegibility" (for ligatures
and kerning-pairs) by default for text sizes above 20px. Could it be a
similar feature?

I did a comparison of the entire inherited computed styles list between
<49px and >49px and there are no apparent CSS changes. -- I was hoping to
find a vendor-specific property.

Around 49px you're probably hitting an internal Skia breakpoint where we
get very, very slow at rendering text.
