When developing AsWing A3, i discovered that the filters works weird. The simpled test code is:

package{
import flash.display.*;
import flash.events.*;
import flash.filters.*;
import flash.geom.Rectangle;
import flash.text.*;
public class TestProj extends Sprite
{
private var sprite:Sprite;
private var cursor:Sprite;
private var text:TextField;
public function TestProj(){
sprite = new Sprite();
sprite.graphics.beginFill(0xff0000);
sprite.graphics.drawRect(0, 0, 100, 20);
sprite.graphics.endFill();
sprite.x = sprite.y = 100;
//if you comment this line, then every thing runs well
sprite.scrollRect = new Rectangle(0, […]
