UGUI 鼠标悬浮UI出现弹框,鼠标在图片边缘出现闪烁

1、背景：鼠标悬浮在UI上出现提示框

public class SpecialParam_list : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{public void OnPointerEnter(PointerEventData eventData){TipBox.Instance.ShowBox(Input.mousePosition, value);}public void OnPointerExit(PointerEventData eventData){TipBox.Instance.HideBox();}}using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class TipBox : UnitySingleton<TipBox>
{SpecialFyALand_Panel fyALand_Panel;GameObject tioObj;public float offset = 1;[SerializeField]private float threshold = 1f;public  void ShowBox(Vector2 pos, string ac  ){if (tioObj == null){tioObj = ResMgr.GetInstance().Load<GameObject>("TipBox", ResourcesType.UIPrefabs);tioObj.transform.SetParent(GameObject.Find("Canvas").transform);tioObj.transform.SetAsLastSibling();} TipBoxInfo tipBoxInfo = tioObj.GetComponent<TipBoxInfo>();tipBoxInfo.InitData( ac );tioObj.SetActive(true);tioObj.transform.SetAsLastSibling();tipBoxInfo.transform.position = new Vector2(pos.x, pos.y) + new Vector2(0, 0) * offset;//tipBoxInfo.transform.position = new Vector3(pos.x, pos.y, 0) + new Vector3(963, 539, 0) * offset;}public void HideBox(){if (tioObj != null&& tioObj.activeSelf)tioObj.SetActive(false);}
}

2、鼠标一旦出现在图片边缘弹框就会不停的闪烁

3、解决方案：将弹框包含所有的物体的RaycastTarget去掉
