+jdufault@, not sure if it's a views-based issue.

Seems like a regression to me.
From video attached it looks like the problem was happening in oobe? (Because the version string is not inside the sign-in dialog, which is another bug we need to fix...). Maybe something wrong after the loading is timeout[1], but I didn't get to repro so far so I can't be sure.

Could this be related to https://chromium-review.googlesource.com/c/chromium/src/+/1023590?

While sync consent screen is waiting for the status update it might show a blank screen?

This is not always reproducible but I did see the blank screen in a very short period on Peppy. 
We are trying to go to beta this week, we need this fixed in the next 24 hours.

David can we get this repro locally? We can't fix this if we can't repro.

That's actually very strange, because previously there was spinner displayed from "Add user" screen (after Cl in #9) . I think that adding a designated "Please wait" is a correct way to fix this issue, but where has the previous one gone?
