I have this problem on my blog. The menu-typo is integrated via @font-faces
and dances around like the hollywood-sign. It has a 3degree-rotation and on win it works perfectly but on mac it has no correct base-line. Are there ways to fix this?
Here's a screenshot (Mac, Chrome):
The design is currently located at http://blog.desiign.de/. By the way, in Windows the rotation works perfectly.
This has become a bit of a golden hammer lately, but forcing hardware acceleration on the layer ensures that the font is rendered correctly:
nav#category-nav {
-webkit-transform-style: preserve-3d;
}
This fixes your problem in Chrome 13 and Safari 5.1 - the browsers I could test.
