text rendering on mobile air app

Hi, I'm facing a problem while rendering text on a mobile app. I'm createing a textfield and when it shows the text seems strange - readabel but strange. Also, when I zoom the text the font seems to be replaced by a bitmap representation of it since it becomes pixelated and blurry. The textfield properties I'm setting advanced antialias and embed fonts to true. I'm embedding the font into the application and this is working, since the text is shown in the correct font.

Oh, and the app is being rendered on cpu mode and stage is on HIGH quality.

Any clues about that?
