title: OpenGL 2D Shape Issue
body: <p>I'm trying to make shapes with OpenGL in LWJGL but every time I do it, it makes this triangle dent in it.</p>
  
  <p>The Code:</p>
  
  <pre><code>//The Window Is 800 Wide And 600 Tall
  GL11.glBegin(GL11.GL_QUADS);
  GL11.glVertex2i(0, 0);
  GL11.glVertex2i(800, 0);
  GL11.glVertex2i(0, 600);
  GL11.glVertex2i(800, 600);
  GL11.glEnd();
  </code></pre>
  
  <p>The Result:</p>
  
  <p><img src="https://i.stack.imgur.com/oGQ9o.png" alt="The OpenGL Fail"></p>
  
  <p>Also, the code was a lot bigger then that. I just put the code that draws the shape.</p>
