Poor text quality when adding with actionsctipt

1

Hi,

I make my textfield and wrap it in a movieclip and add it to the stage, and it looks great. As soon as I make it a linkage class (ClientText) and add it with

            var clientText = new ClientText ();    
            clientText.x = 75;
            clientText.y = 60;
            addChild(clientText);

It gets really rough (see image attached) any idea how I can fix this?
