Dev Flutter/Latest Dart plugin and 2020.1 IntelliJ seems to be awfully "flashy".

Steps to Reproduce

I was just editing along, and had the feeling that I needed sunglasses. 😃

Each time I type a character, the code flashes between syntax highlighted and fully analyzer highlighted:

I’ve tried uninstalling and re-installing both plugins, clearing cache and restarting, and removed my .dartServer directory and restarted.

Version info

I’m on the dev channel for the Flutter plugin. Not sure why doctor says I don’t have the plugins installed, because I do, the Flutter plugin says it is at 46.0.3-dev.1, and the Dart plugin says it is at 201.6668.124.
