Hi, I notice severe lag/freezing when typing in dart files in my flutter project. The lag is not there if I disable the Dart vscode extension.

Sometimes inputs are lost, most often when pressing escape (I use the vim plugin) and then quickly do some vim commands. I assume it is because the CPU is busy, since the extension host seems pinned at 25% (on a quadcore system).

I use an overclocked i5-6600k and 32GB of RAM, so my system specs should be more than enough.

I did some typing in a file and recorded the CPU profile which is attached below.

Any ideas what causes this?
