We didn't do anything special in Qt 4.4. We may have plugged a specific 
hole that you were seeing.

In Cocoa, we use CoreText, while Carbon still is using ATSUI, so these 
holes may have shown up again. Could you be a bit more specific about 
what regression are you seeing and what you are doing?

Thanks,
