When you open the privileges page and select a privilege with a long name, the percentage of the next privilege is aligned incorrectly. This happens for example when you choose “cast close and reopen votes” privilege.
Always reproducible with Firefox 3.6.12, Internet Explorer 8.0.7600.16385 and Chrome 8.0.552.215 on Windows 7.
My guess is that the problem itself had been always there, but the font used during the beta was not wide enough to trigger this glitch whereas the font used in the new design is wide enough to trigger it.
[Added: Another cause seems to be that the font used to show the percentage is (probably) higher than the vertical space between rows. Actually, this table is constructed by using floats instead of using a simple <table> element and, if I understand the intent correctly, the very reason for this is to handle the horizontal overflow nicely. The font being higher than the vertical space destroys this gimmick and produces a worse result when the horizontal overflow occurs.]
