this is common to see in IE7 -- IE7 has support for alpha png8 (iirc), but gifs w/ alpha still use filter: in IE7 (somehow) or vice versa. The aliasing is a result of some odd combination of ie7 support for png / alpha and using filter:

just a thought.

ps. if affects text being faded w/ no matte (direct background color in text case)

you can also see this in IE7 during the fadein of the circles in the mojo demo.

(In [13429]) IE7 supports png images but they look weird during fade-in, so stop using them, at least for tooltip. Fixes #6555.
