production mode causes flickering

[toloudis]

Description

Currently we always build in developer mode. Modifying webpack.dev.js to use production mode reveals some flashing/flickering during time series playback.

Expected Behavior

We would like to be able to build in production mode for production builds. And the app should function ideally the same or better.

Reproduction

Modify webpack.dev.js to use production mode (can do this conditionally on env.env === "production" ? "production" : "development" )
