OnPointerExit fired right after OnPointerEnter

I am implementing a HUD system where I'd like to display a label over a POI (Point of interest).
Environment: Unity 2018.1.0b13 and PC standalone.

I've created a TextMeshProUGUI object and set the TAG to HUD_TEXT.
Added PhysicsRaycaster to Main Camera.
Created a 3D object (cube) and add POI_Inputs.cs script to it. (see below).

Run in Editor.
Label is blinking and in debugger you can see a OnPointerExit method fired when the pointer is over the cube.

Code (CSharp):

1. using TMPro;
2. using UnityEngine;
3. using UnityEngine.EventSystems;
4.  
5. public class POI_Input : MonoBehaviour,
6.                         IPointerEnterHandler,
7.                         IPointerExitHandler
8. {
9.  
10.     private Transform hudTransform;
11.     private TextMeshProUGUI hudText;
12.     private Camera cam;
13.     private float near;
14.    
15.     private void Awake () {
16.         var ob = GameObject.FindWithTag ("HUD_TEXT");
17.         if (!ob) return;
18.        
19.         hudText = ob.GetComponent<TextMeshProUGUI>();
20.         hudTransform = ob.GetComponent<Transform>();
21.         hudText.enabled = false;
22.         cam = Camera.main;
23.         near = cam.nearClipPlane;
24.  
25.     }
26.  
27.     public void OnPointerEnter(PointerEventData eventData)
28.     {
29.         Debug.Log("OnPointerEnter " + name);
30.         hudTransform.position = new Vector3(eventData.position.x, eventData.position.y, near);
31.         hudText.text = name;
32.         hudText.enabled = true;
33.     }
34.  
35.     public void OnPointerExit(PointerEventData eventData)
36.     {
37.         Debug.Log("OnPointerExit " + name);
38.         hudText.text = "";
39.         hudText.enabled = false;
40.     }
41. }

Please provide you suggestions and comments.

P.S. Same behavior with UI.Text

 

Resolved! Using OnMouseEnter and OnMouseExit instead of OnPointerEnter and OnPointerExit.
