Run attached application.

To reproduce:
1. In first stage click "Init".
2. In the second click "Win"
3. In the third click "App"
4. In the fourth click "None"

I see intersection of all windows. (every next is intersected with the previous one).

I created this app for windows OS first, and it was written in a such way, so every new scene will not intersect with the previous. So I writed:
    private void changeStageSizes(){
        switch(renderType){
            case LIST:
                stage.setWidth(width);
                stage.setHeight(height); // Look here
                stage.setX(initialX + (counter-1));
                stage.setY(initialY + (counter-1)*height); // and here
//...
counter++

It works for winOS: windows don't intersect. that is not true for linux.
