I tried this method in component Cell

shouldComponentUpdate(nextProps, nextState) {
  if (this.props.name !== nextProps.name) {
    console.log("Name **********************");
        return true;
    }

      console.log("False ****************************");
      return false;
    }

After this when I open a tile it's empty also I have installed "why-did-you-update" that display re-render components when loading home it`s ~ 451 re-render when open a tile ~ 1117 PureComponent doesn't work

[vadim9999]

ok, it's working PureComponent and shouldComponentUpdate() I just needed more learn

cool! optimization is an important thing - i like that you learning it also, you can apply your debug to this samples: https://codesandbox.io/embed/0582jolnl https://codesandbox.io/embed/z6ly40071p

i just want to eliminate the possibility that this is an issue, related to package that we're using - because if this is their issue - we can not only solve our trouble - but also contribute to other project

[atherdon]

did we solve this issue, right? at my side - it works better

[vadim9999]

yes
