If I apply a rotation to a text, it will not render anti-aliased in Firefox and Chrome (only in Windows) but it renders correctly in IE. Also, it renders correctly in Chrome and Firefox in Mac OS X.
Here are screenshots comparing three browsers in my Windows 8:
http://d.pr/i/9qeg (Chrome)
http://d.pr/i/r8i0 (Firefox)
http://d.pr/i/crZ7 (IE10)
The CSS transformations for above is simply
transform: rotate(-1.5deg) translateY(-2px);
Here is a fiddle:
Any ideas?
