LWJGL / OPENGL Kriege Depth-Test nicht hin :(

[BDA]

Hey!
Ich versuche grad den Depth-Test in ein paar kleinen Test zum funktionieren zu bringen, aber der mag micht nicht Was habe ich falsch gemacht ;( Wahrscheinlich einfach irgendwo ein Minus zu viel oder so... Zum starten erstelle ich einfach ein neues Objekt dieser Klasse

//Imports sind uninteressant!

public class Window {

	public static final int WIDTH = 1280;
	public static final int HEIGHT = 720;
	public static final String TITEL = "Minaria";

			Display.setDisplayMode(new DisplayMode(WIDTH, HEIGHT));
			Display.setTitle(TITEL);
			Display.create();
		} catch (LWJGLException e) {
			e.printStackTrace();
