Steps to Reproduce

1. go to https://gatsby-forty.surge.sh/
2. click on menu button ( top right corner )

Inspect in profiler

I have attached the performance profiling data ( profiler.firefox.com ) the new one :p

Actual results:

Paint takes a lot of time making the transition feel very janky

Expected results:

transition should have been very smooth without blocking that main thread for so long

From the profile this seems to be a Graphics issue.
Weird things I can see at a glance:

• memory usage
• the graphics subsystem seems to wait a lot

I tested this out with WebRender enabled, seems to work better. Clicking on the menu button feels more responsive, transition looks pretty smooth.
