How to solve the problem that there is a short gap in the fast scrolling of vue v-for mobile phone?

I use vue to make a page on the mobile side, and the following problems arise: when
v-for, as long as the internal complexity of the element is relatively complex (if there is only a single layer of div for each item, there will be no problem). There will be a brief gap when scrolling on the mobile side (which will not occur when debugging on the PC side).
preliminary guess is due to Virtual DOM (this didn"t appear in such a list that didn"t have to be done with vue before).
since I am new to vue, I don"t know how to solve this problem.
and v-for should do this scrolling list for most projects as well.
but the solution to similar problems can not be found on the Internet. Am I searching for the wrong keywords?
below is a screenshot of the simple project created to recreate the problem.

the following is the code to create a new project to recreate the problem:

<template>
<div class="bug-list">
  <div v-for="item in list" :key="item.id" class="bug-item">
    <div>{{item.text}}</div>
    <div v-for="child in item.children" :key="child.id">
      <span>{{child.text}}</span>
    </div>
  </div>
</div>
</template>

<script>
export default {
  name: "HelloWorld",
  data() {
    return {
      list: []
    };
  },
  props: {
    msg: String
  },
  created() {
    for (let i = 0; i != 1000; PPi) {
      this.list.push({
        id: i,
        text: ` ${i} `,
        children: [
          { id: 1, text: " 1" },
          { id: 2, text: " 2" }
        ]
      })
    }
  }
}
</script>

<style scoped>
.bug-list {
  position: absolute;
  overflow-y: auto;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: white;
}
.bug-item {
  border: 1px solid -sharpddd;
}
.bug-item:nth-of-type(2n) {
  background-color: -sharpeee;
}
</style>

this has nothing to do with Vue. Did you write to scroll to the end before loading the contents of the following list

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
