CSS text-rendering property causing issues with headlines in Chrome

[OriginalEXE]

I am running Google Chrome Version 30.0.1599.114 on latest Kubuntu and I have issues with headlines on wordpress.org website.

Issue can be spotted on this url: ​http://core.trac.wordpress.org/
Screenshot of the issue (also attached): ​http://pbrd.co/1dt1bxh

It appears that this css rule is causing the issue:

#headline h2 {
text-rendering: optimizeLegibility;
}

When set to "auto" instead of "optimizeLegibility" it no longer has such issue.
I can confirm that the issue is not happening in latest FF on the same OS.

Let me know if you need anything else.
