Actually, I noticed this some time ago, but never found it bothersome until this most recent project. Under most circumstances it actually creates for a rather visually pleasing web browsing experience, but falls noticeably short with white text on a dark-ish background.

The fix for web authors, it seems, is quite simple. Applying a wee bit of CSS magic to the objects’ text-shadow attribute will do the trick. I personally add it to the body object, but thanks to the wonders of CSS, this effect could be added or removed to individual objects as you wish.
text-shadow: 0 0 0 #000;
Now your type will look uniform across all browsers, without any inherent font smoothing, anti-aliasing, or silent visual adjustments.
