React dev builds are terribly slow at rendering large lists. Open Slack and scroll up for about a minute. It becomes unresponsive very quickly.

I don't understand how deploying React's dev build would help anyway... Do they regularly run into bugs where they need to step into React code?

scrolling up also makes CPU usage spike on chrome (and by extension, on the electron app). This doesn't happen with Firefox
