(windows eXperience) start menu text issue

i'm on the latest release of windows eXperience and i've just noticed, after switching the theme to zune *anything that isn't blue, olive or silver, the start menu entries for internet explorer and outlook have the wrong text spacing, causing the I and the O to jump to the first line:

it looks just fine on the regular blue theme, so i'm not really sure what's causing it on zune*...

edit: i'm stupid, turns out this affects embedded and royale too
