title: Actions() in LibGDX accumulate error whith every click on a sprite
body: <p>Actions accumulate an error that increases with each click.</p>
  
  <p>I am making a game. When I click on the sprite a dialog box comes out. This dialog box comes out with the animation that I do through Actions(). Initially, the dialog box smoothly opens and scales and also smoothly closes. But after about 10 openings and closures of the dialog box, an error becomes noticeable. The dialog box begins to jerk open and close. The more I click on the sprite, the more torn the animation of dialog box turns out.</p>
  
  <pre><code>@Override
  public boolean touchDown(int screenX, int screenY, int pointer, int button) {
      vector2 = new Vector2(screenX, Gdx.graphics.getHeight() - screenY);
  
  if (sprite_1.getBoundingRectangle().contains(vector2)) {
      switch (serverClass.point1) {
          case 0:
              Gdx.app.log("1", "drops");
  
  win_dialog_alpha_white.addAction(Actions.fadeIn(.2f)); //this window covers all sprites
  stage_dialogs.addActor(win_dialog_01_1);
  
  win_dialog_01_1.setModal(true);
  
  win_dialog_01_1.addAction(
      Actions.fadeOut(0));
  
  win_dialog_01_1.addAction(Actions.parallel(
      Actions.fadeIn(.2f)
      , Actions.scaleTo(1.05f, 1.05f, .2f)));
  
  win_dialog_01_1.addAction(Actions.sequence(
      Actions.delay(.2f)
      , Actions.scaleTo(1, 1, .2f)));
  
  button_close.addListener(new ClickListener() {
  @Override
  public void clicked(InputEvent event, float x, float y) {
      win_dialog_alpha_white.addAction(Actions.fadeOut(.3f));
      win_dialog_01_1.setModal(false);
      win_dialog_01_1.addAction(Actions.parallel(
          Actions.fadeOut(.4f)
              , Actions.scaleTo(1.05f, 1.05f, .2f)));
      win_dialog_01_1.addAction(Actions.sequence(
          Actions.delay(.2f)
              , Actions.scaleTo(1, 1, .2f)));
                      }
      });
      break;

  <p>The "win_dialog_01_1" is a separate class (extends Window), but the button  "button_close" created in a main class and then added to the instance of "win_dialog_01_1".</p>
  
  <p>I can not finde where the error is accumulate.</p>
