This bug has been around for a really long time. It exists in Safari 6 and nightlies. Go to the link and either wait for the slideshow to change to the next or click the dots at the bottom center and watch the menu text get thinner and then go back to the correct thickness. Similar thing happens here: http://www.telemedamerica.com/what-is-telemedicine/ As the slide changes, the menu text, breadcrumb text right below and the "Excellent Support Staff" heading down below get thinner and then go thick again. Even further below the box containing "Let us help improve…" also does the same thing. http://www.kosmont.com Ignore the disappearing menu text since that's due to another reported bug. Rollover the menus and the menu to the right of the selected one gets thinner. It used to be more pronounced here but I found forcing… * { -webkit-font-smoothing: subpixel-antialiased !important; } …minimized the amount of difference in the ant-aliasing shifts. Disable that style in Web Inspector and you'll see a more pronounced text change.
