The README.md says:
For now Display Builder works only in dev mode and poorly with Drupal cache.
It must be tested only with:
- **NO JS aggregation** (will fail Data from a field on entity view)
Other settings like performance or development settings can be production oriented.
_Note_: Enabling your component based theme before enabling Display Builder will help load fixtures.
Make our AJAX works with JS aggregation enabled.
