First of all, remove the multiplication in the width and height of the GameWindow and use total numbers instead, we experienced some strange outcomes related to this.
Have you centered your loaded level in your game scene? If not, your level will start at 0/0 of your game scene and expand to far down instead of half the way above and half the way below the game scene on other display ratios.
If that doesn’t help, I will have a closer look at your code tomorrow.
