Applying M-68 milestone per email discussion with ellyjones@. Pls change it if milestone is incorrectly applied. 

MacViews triage: this reproduces. Over to sdy@ for M-68.

Yandex (or Whale - I forget - maybe both) just made this transparent instead. But that's not ideal. It does weird things with shadows. However, if a web page has a super-slow layout we can time out trying to get a frame from the renderer to fill in pixels anyway. MacCocoa currently paints white in that case.

But the MacViews toolbar area should "never" time out - I think the synchronisation step with the webcontents is interfering. Work for Viz has started submitting ~tokens for each frame -- I think we can use that somehow.

FYI: Starting 04/13 M68 will be in canary, M68 Dev promotion will be on 04/26.

Attache a diagnostic video here.

The blue is where we fail to draw in time -- we give the UI 50 msec to draw -- I think we should massively increase this (there's no sense in drawing anything when we don't have UI at the right size).

The cyan is the issue that sdy@ fixed in the renderer with NSDisableScreenUpdates.
