{lwjgl} help on understanding openGl initialization

Hello,
i’ve been trying to solve the problem am facing with rendering Font using SlickUtile in Lwjgl, and it appears that the issue is due because of the OpenGL initialization (the low FPS was because i initialize variable inside the game loop :stuck_out_tongue: )
anyway,
i tried to render a text in a simple pong game, and the result was this (the white rectangle is the text) :

that result happens when i use this openGl initialization :


private void initGL() {
		GL11.glMatrixMode(GL11.GL_PROJECTION);
		GL11.glLoadIdentity();
		GL11.glOrtho(0, 800, 0, 600, 1, -1);
		GL11.glMatrixMode(GL11.GL_MODELVIEW);
		GL11.glClearColor(0.0f, 0.0f, 0.0f, 1.0f);

	}

and if i use this initialization (from the FontExample of the lwjgl wiki )


GL11.glEnable(GL11.GL_TEXTURE_2D);
		GL11.glShadeModel(GL11.GL_SMOOTH);        
		GL11.glDisable(GL11.GL_DEPTH_TEST);
		GL11.glDisable(GL11.GL_LIGHTING);                    
 
		GL11.glClearColor(0.0f, 0.0f, 0.0f, 0.0f);                
        GL11.glClearDepth(1);                                       
 
        GL11.glEnable(GL11.GL_BLEND);
        GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
 
        GL11.glViewport(0,0,width,height);
		GL11.glMatrixMode(GL11.GL_MODELVIEW);
 
		GL11.glMatrixMode(GL11.GL_PROJECTION);
		GL11.glLoadIdentity();
		GL11.glOrtho(0, width, height, 0, 1, -1);
		GL11.glMatrixMode(GL11.GL_MODELVIEW);

i get this result :
