title: Detecting hovering on button event on Oculus Quest (Unity3D)
body: <p>Stack:</p>
  
  <ul>
  <li>Oculus Quest</li>
  <li>Unity 2019.3</li>
  <li>Oculus VR Integration</li>
  <li>macOS Catilina</li>
  </ul>
  
  <p>I have a Unity scene with a VR interface composed by a Canvas (World Space coordinates) and two buttons.  The canvas has attached an OVR Raycaster objects which uses a laser pointer. Overall it works well, but when I try to intercept the event produced by hovering the laser pointer on the button, I can get only the click event.</p>
  
  <p>I'm using the following script (attached to the button):</p>
  
  <pre><code>using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using UnityEngine.EventSystems;
  public class VRButton : MonoBehaviour, IPointerEnterHandler, IPointerClickHandler, ISelectHandler
  {
      // Start is called before the first frame update
      void Start()
      {
  
      }
  
      // Update is called once per frame
      void Update()
      {
  
      }
  
      public void OnPointerEnter(PointerEventData eventData)
      {
          Debug.Log("Enter!");
          transform.localScale *= 1.2f;
      }
  
      public void OnPointerExit(PointerEventData eventData)
      {
          Debug.Log("Exit!");
          transform.localScale /= 1.2f;
      }
  
      public void OnPointerClick(PointerEventData eventData)
      {
          Debug.Log("Clicked!");
      }
  }
  </code></pre>
  
  <p>The strange thing is that both OnPointerEnter and OnPointerClick get called when I point the button with the laser and click. Just hovering the doesn't trigger any event (nor OnPointerExit or OnPointerEnter). </p>
  
  <p>This is my ADB log:</p>

  <p>How can I fix it?</p>
