HTML5 fullscreen

Questions
1

I’ve been doing some testing with my games and noticed laggy frames when switching to HTML5 fullscreen. The lag also persists for a few seconds after exiting fullscreen and then everything seems to return to normal.

I did a quick almost empty example here:

I also tested in Unity as I thought it might be because of hardware specs/browser:

What might be the cause and what could I do to fix this?
