    Severe Artifacts in AIR beta 15 in BitmapData.draw()

      The latest beta has introduced a serious bug in BitmapData.draw() - when drawing a bitmapData onto another using a transformation matrix, the pixels are getting messed up:

       

      Example:

      package

      {

        import flash.display.Bitmap;

        import flash.display.BitmapData;

        import flash.display.Sprite;

        import flash.geom.Matrix;

       

        public class Air15ArtifactDemo extends Sprite

        {

        public function Air15ArtifactDemo()

        {

        stage.scaleMode = "noScale",

        stage.align = "TL";

       

        var map:BitmapData  = new BitmapData(1024,1024,true,0);

        var map2:BitmapData  = new BitmapData(500,500,true,0xff000000);

       

        var m:Matrix = new Matrix();

        m.translate(-250,-250);

        m.rotate(Math.PI*0.25);

        m.scale(1.3,1.3);

        m.translate(512,512);

       

        map.draw(map2,m,null,"normal",null,true);

        addChild(new Bitmap(map,"auto",true));

        }

        }

      }
