真机上好像没有这个问题。可以使用以下代码复现问题（通过Taro CLI初始化一个项目，拷贝以下代码到page/index/index.tsx，启动后点击"ceshi"）

import React, { useState } from "react";
import { View, Text, Map } from "@tarojs/components";
import "./index.scss";


const Index: React.FC<{}> = ({}) => {
  const [test, setTest] = useState(false);


  return (
    <View className="index">
      <Map longitude={115.225173} latitude={23.213408} />
      {test && <Text>asd</Text>}
      <View
        onClick={() => {
          setTest(true);
          console.log("clicked");
        }}
      >
        ceshi
      </View>
    </View>
  );
};


export default Index;
