GUI.Label overlaps and looks fuzzy in built game but looks fine in Unity Game View

Heres the script:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Multiplayer : MonoBehaviour {
5.  
6.     void Start () {
7.         Network.Connect("127.0.0.1", 26500);
8.     }
9.  
10.     void OnFailedToConnect(NetworkConnectionError error) {
11.         Network.InitializeServer(10, 26500, false);
12.     }
13.  
14.     void OnGUI () {
15.         if(Network.isServer) {
16.             GUI.Label(new Rect(5, 5, 200, 50), "You are the server");
17.         } else if (Network.isClient) {
18.             GUI.Label(new Rect(5, 5, 200, 50), "You are a client");
19.         } else if (!Network.isServer && !Network.isClient) {
20.             GUI.Label(new Rect(5, 5, 200, 50), "You are not connected");
21.         }
22.     }
23. }

Heres how it looks in Unity:


Heres how it looks when its built:


Please help guys!
Thanks for reading

 

Looks to me like you don't have anything clearing the background, so the anti-aliasing is becoming thick white. Do you have an active camera in the scene with a clear flag set (Skybox or solid color)?
