React-virtualized, List is Flickkering/lagging when scrolling

I am experiencing some problem when i scroll through my list. Also notice the huge space at the bottom. See video : https://vimeo.com/215349521

As far as i can see, im not making any huge mistakes. But i do belive the problem is due to the CellMeasurer.

Chrome version: 58.0.3029.81

class PromotionList extends Component {

constructor(props) {
    super(props);

    this.cache = new CellMeasurerCache({
        defaultHeight: 100,
        fixedWidth: true,
    });

    this.rowRenderer = this.rowRenderer.bind(this);
}

componentWillMount() {
    this.props.fetchPromotionsIfNeeded();
}

rowRenderer({ index, parent }) {
    const { promotions } = this.props;
    const data = promotions.list[index];

    return (
      <CellMeasurer
        cache={this.cache}
        columnIndex={0}
        key={uuid.v1()}
        parent={parent}
        rowIndex={index}
      >
        <BlobItem
          key={uuid.v1()}
          type={BlobTypes.promotion}
          data={data}
          onClick={this.props.onItemClick}
          index={index}
        />
      </CellMeasurer>
    );
}


render() {
    const { promotions, previewSize } = this.props;

    return (
      <List
        height={300}
        width={previewSize.width}
        rowCount={promotions.list.length}
        deferredMeasurementCache={this.cache}
        rowHeight={this.cache.rowHeight}
        rowRenderer={this.rowRenderer}
        className="blobList"
      />
    );
}
}

Found the solution after reading through the documentation. Just needed to add the style in the "rowRender" method:

rowRenderer({ index, parent, style }) {
  const { promotions } = this.props;
  const data = promotions.list[index];

  return (
    <CellMeasurer
      cache={this.cache}
      columnIndex={0}
      key={uuid.v1()}
      parent={parent}
      rowIndex={index}
    >
      <BlobItem
        key={uuid.v1()}
        type={BlobTypes.promotion}
        data={data}
        onClick={this.props.onItemClick}
        index={index}
        style={style}
      />
    </CellMeasurer>
  );
}
