A potential culprit between r102347 and r102372 is r102366

http://crrev.com/102366  : Skia roll to 2303

Mike, could your fix for the intl2 page recycler regression lead to this? I'm talking about this change in Skia:

Comment 15 by bashi@chromium.org, Sep 27 2011

I build Chromium with Skia r2300 and didn't see the regression. It looks like skia r2301 is the cause.

Thank you for confirming my hunch :-). Assigning to reed@  

Just to say, while Chinese website cannot show up correctly, I found large text and bold text usually more readable than others. Don't know why.

Comment 18 by reed@google.com, Sep 27 2011

looking at it now

Comment 19 by reed@google.com, Sep 27 2011

I saw inverted text, but have a fix pending. See screenshot -- does this look correct?

#19's creaders.png does not appear correct, many/most of the characters are improperly overlapping. See the initial poster's attached image.

I can confirm this issue on Win7-64 for Japanese script -- this bug makes pages largely illegible.

I can confirmed this issue on Win7 64bit running Google Chrome 16.0.891.0 (Official Build 102650) dev-m.  It renders http://zh.wikipedia.org/ like this.

Also, should it be in the Compat-Web Area?
For Chinese, I solved it by changing the  font-family in the "User StyleSheets"
body,*{
font-family: "微軟正黑體" !important;
}
But it only works in 16.0.893.0 (102888) canary but not in 16.0.891.0 (102650) dev

Comment 57 by Deleted ...@, Sep 28 2011

This is a bug transfer me back to the age of IE T_T
A quick fix for this issue is to disable clear-type in windows (uncheck the box for clear type under control panel, display, then go through the selection without choosing anything.

been to zh.wikipedia.org, www.google.co.jp,www.google.co.kr. text rendered correctly on those websites when clear-type is off.

Comment 59 by Deleted ...@, Sep 28 2011

disabling clear-type does not work for me, Windows 7 Home Premium 64 Bit SP1 
Disabling the clear-type does not work for me too. The user stylesheet fix also failed even with the --enable-user-stylesheet parameter.  Google Chrome Build 102650.  Win7 Ultimate 64bit SP1.
just out of curiousity, can you go back and see if the check-box for clear-type has been unchecked? i made the silly mistake when i have been told this fix, that i clicked on the box to uncheck and go through those selection processes, but for some reasons the clear-type function was still on as the box was still ticked in windows.

btw, i have 32bit version of windows7, that may also be the reason why it works on my machine but not on yours.

Comment 62 by Deleted ...@, Sep 28 2011

its unchecked =(

hope they release a new build to fix this asap...its really annoying that i have to zoom to 200% to read Chinese characters...

Comment 63 by js...@chromium.org, Sep 28 2011

Please, note that this bug was fixed in the trunk (tip of tree) yesterday. It'll show up in next dev channel (which will be released next week). Beta and stable channels do not have this problem.

Comment 64 by sun...@gmail.com, Sep 28 2011

@kitwailee have you restart your chrome?
it won't take effect before chrome is restarted
it will

Is there any way to release a dev channel update asap with this patch and another very critical patch made this week? 

I'm wondering how this passed Webkit layout tests and our QA process before 16.0.891.0.  

Comment 73 by js...@chromium.org, Sep 29 2011

For webkit layout tests, perhaps we have to add a Windows-only test that explicitly specifies some of old Windows fonts (non-Clear type fonts) .
