В чём проблема гличей при скролле с использованием react-window?

Question

[kirillleogky]

Я хочу сделать виртуализацию рядов при скролле (чтобы показывались данные при скролле)
Но при скролле сейчас гличи ужасные появляются

Подскажите в чём дело?

Компонент с таблицой (там и используется react-window):

import React, { Component } from "react";
import Grid from "@material-ui/core/Grid";
import Box from "@material-ui/core/Box";
import "./table.css";
import { connect } from "react-redux";
import actions from "../../actions";
import PropTypes from "prop-types";
import sort from "./sort";
import { FixedSizeList } from 'react-window';

function TitleColumn(data) {
  return (
    <Grid item xs={1}>
      <Box className="title_elem">
        <h3
          className="table_title-text"
          onClick={sort.bind(null, `${data.title.toLowerCase()}`, data.props)}
        >
          {data.title}
        </h3>
        {data.props.fourthData.data === `${data.title.toLowerCase()}` ? (
          <p>{data.props.fifthData.data}</p>
        ) : null}
      </Box>
    </Grid>
  );
}


class Table extends Component {
  render() {
    const data = this.props.info;
    const Row = ({ index }) => {
