Sometimes, the characters disappeared randomly. See following testcase (needs Japanese font): http://bugzilla.mozilla.gr.jp/attachment.cgi?id=3175 If you cannot see this bug, resize the browser, you may see this bug.
I think that this is a bug of cairo. If following patch applied, we cannot see this bug (but the text is not beautiful, we cannot use this patch.) http://bugzilla.mozilla.gr.jp/attachment.cgi?id=3177 And I think that we cannot see this bug in very simple text, e.g., only Japanese characters, only alphabets. This bug can be reproduced on many sites and many times. We should block Fx3 release by this bug.
Whiteboard: cairo
And, this bug is tested on bugzilla-jp too. http://bugzilla.mozilla.gr.jp/show_bug.cgi?id=5138

(In reply to comment #8) > that should probably be submitted upstream instead. Should I submit to cairo community?

This is a new patch. This removes only one line. But I don't know whether this is correct. Why current code has this line?

Comment on attachment 223019 [details] [diff] [review] Patch rv5.0 Vlad: The bug 6955 of freedesktop.org was fixed. Should we wait next upgrade our cairo code? Or, can I land the patch if I create the patch from http://gitweb.cairographics.org/?p=cairo;a=commitdiff;h=7e457cb4c1e69670f27e3e8e134a9e32a8f75788;hp=6a58658b73924fa6897bd1e290d754ce1df44b0d ?

Since bug 344571 has been fixed, this isn't reproduced. I think this should be resolved/fixed
