Help: Dynamic VS Static TextField

Hi there,

i found some strange behavior when zooming movieclips with nested textfields.

Problem:
I got a movieclip with some dynamic textfields on it and embeded the desired font. To get the effect of fading in i set scaleX/scaleY to 0.5 and lets tween it back to 1.0 (changing the alpha from 0.0 to 1.0 also). But when the movieclip zooms in the the characters starts to jiggle instead of growing smooth. If i set the textfield to static and embed the font anything works fine - no jiggle. Any ideas?

I am working on a mac with flash cs3.

Check the attached sample (quick and dirty coded, fla+swf with font embedded) to see what i mean.

@biznuge: So you can call me a spambot - here’s the url with the swf (which i am not able to post here): http://www.unshape.com/fonttest.swf

 
var mc:MovieClip = new MovieClip();
var txt:TextField = new TextField();
txt.embedFonts = true;
var fmt:TextFormat = new TextFormat();
fmt.kerning = true;
fmt.size = 30;
fmt.font = new uni_font().fontName;
fmt.color = 0x000000;
txt.defaultTextFormat = fmt;
txt.autoSize = TextFieldAutoSize.LEFT;
txt.antiAliasType = AntiAliasType.ADVANCED;
txt.text = "THIS IS DUMMY CONTENT";
mc.addChild(txt);
con.addChild(mc);
mc.y = 50;
con.alpha = 0.9;
con.rotate = 1;
var timer:Timer = new Timer(100, 100);
timer.addEventListener(TimerEvent.TIMER, onEnterFrameEvent);
timer.start();
function onEnterFrameEvent(event:TimerEvent):void {
 con.width += 10;
}

I hope anyone got a clue.

tia, rockwell
