3D Text (TextMesh) not updated/redrawn every frame (android only)

Hi.

When I try to change a TextMesh's text every frame on Android, the text that is displayed on the scene is sometimes not refreshed (redrawn?). Does anyone know why, and know a solution to this?

Conditions:

• This doesn't happen on PC. (I did not test on iPhone)

• textMesh.text correctly returns the text that should be displayed. (it's just not drawn)

• This doesn't happen with GUIText.

Smallest sample project: Uploaded here.

This is just a simple scene with a camera, a 3D Text and a GUIText. When you touch the screen, the text is changed each frame during the next 10 frames.

• On Android: the text is correctly displayed for GUI text, but not for 3DText.

• On PC: no problem for both.

This is the script used to update both texts:

 using UnityEngine;
 using System.Collections;
 
 public class NewBehaviourScript
  : MonoBehaviour
 {
  int _currentVal;
  int _targetVal;
  
  void Start ()
  {
  _currentVal = 0;
  _targetVal = 0;
  }
  
  bool _HasTouched()
  {
 
 #if UNITY_EDITOR
  return Input.GetMouseButtonDown(0);
 #else
  if (Input.touchCount == 0)
  return false;
  TouchPhase phase = Input.GetTouch(0).phase;
  return phase == TouchPhase.Began;
 #endif
  
  }
  
  // Update is called once per frame
  void Update()
  {
  if (_HasTouched())
  _targetVal += 10;
  
  if (_currentVal < _targetVal)
  _currentVal++;
 
  TextMesh textMesh = gameObject.GetComponent<TextMesh>();
  if (textMesh != null)
  textMesh.text = _currentVal.ToString() + "%";
  GUIText guiText = gameObject.GetComponent<GUIText>();
  if (guiText != null)
  guiText.text = _currentVal.ToString() + "%";
  }
 }
