Looks pretty good to me? Do other chrome:// pages not show theme color?

Comment 3 by lgar...@chromium.org, Jun 28 2017 

Nope!
This page also used to have a white background.

Summary: Pages without background sometimes show theme color instead of white (was: chrome://interstitials has theme background color instead of white)
I just observed this on a webpage with a white background. Looks like a more general rendering issue for pages without a background.

(Note that I have JS disabled, and that page sets the background color dynamically.)

Is it possible you have another extension causing this? Does it repro in incognito?

Comment 6 by lgar...@chromium.org, Jun 29 2017 

It doesn't reproduce deterministically at all, so it's hard for me to investigate.

Almost certainly some race condition in the new code to avoid white flashes.

Comment 8 by lgar...@chromium.org, Jun 29 2017 

If it helps, I have a tab open right now that reproduces reliably on refresh.

Comment 9 by chrishtr@chromium.org, Jun 29 2017 

Web pages always have background colors. You must be seeing a situation
when the background does not get updated property to the page's background.

Comment 10 by chrishtr@chromium.org, Jul 11 2017 

I can't reproduce this on the latest canary. Do you have a specific sequence
that still reproduces the issue?

Comment 11 by lgar...@chromium.org, Jul 11 2017 

It's rather non-deterministic. :-/

I'm okay with closing this for now and reopening if I ever see it again.

Ok then.

Observed on Chrome 61.0.3159.5

I opened a new tab and pasted the (local test) URL very quickly.

Once more. First tab in an incognito window. It feels like this is much more likely on the firs tab of a window.

I still can't reproduce this. Can you?
