Question show page
Both Jason Salaz and I have tested this in Chrome and do not see the clipping. To isolate the issue, can you try making a new user account on your Mac and try seeing if Chrome there has the same issue? You also will want to try disabling any extensions or user scripts you have if it's not just a bad render as your browser changes the font size larger and smaller. The new account will help with getting back to the Chrome default fonts and sizes as well as not have any content cached.
