Unity3d Texture2D.ReadPixels problem when convert to sprite.

Hi, I am develop a game with capture screen feature. so i use Texture2D.ReadPixels and convert it to spite so that i can assign my screenshoot to Unity UI.

this is my code

     public GameObject UiDisplay;
 
 
     void OnPostRender() {
             Texture2D tex = new Texture2D(Screen.width, Screen.height);
             tex.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
             tex.Apply();
             UiDisplay.SetActive(true);
             UiDisplay.GetComponent<Image> ().sprite = Sprite.Create(tex, new Rect(0.0f, 0.0f, tex.width, tex.height), new Vector2(0.5f, 0.5f), 100.0f);;
             grab = false;
         
     }

everything work fine, but when i capture screen and there is object with transparent texture like tree. the result is like picture bellow. alt text
