This is a known issue associated with allocating a new surface on every navigation. We hope to address this in M67 with child allocated IDs. Adding some relevant folks.

I should also add that timeTo*Paint are generally bad metrics because they don't measure actually time to presenting a frame to the display.

Thanks, based on #5 and #6, I'm inclined to let this one sit.
