[Evergreen-general] Inconsistent White Screens with Hatch

[John Amundson]

Thanks for the detailed reply, Dan. All good information to have.

We're going to try Garry's solution and see if it works: "Try going into
Chrome settings -> performance and turn off preload pages." So far so good,
but it's only been a few minutes.
