Bug Description

I have a webapp that I modified to use the new colored splash screen. So then I matched to color on the splash screen with the website's "loading" screen. The desired effect would be that the Ubuntu loading would then fade to the webapp's loading without the user really noticing. What happens though is that the Ubuntu loading screen is seen, then the screen turns white, and then the website's loading screen is shown. It would be nice to remove this white flash so that the experience feels more continuous.

Ideally, we’d need some sort of signal from oxide when the rendering starts, so that we delay showing a blank webview until after rendering has started. Not sure this is doable/desirable in oxide though. Alternatively, a cheap solution would be to delay showing the webview until after the initial page has fully loaded, but this might result in a seemingly longer load time.

I wonder if we could use (at some point) the upcoming navigation transition api/feature that is upcoming in blink:

https://code.google.com/p/chromium/issues/detail?id=370696

and basically specifically addresses this (well, apparently from quickly reading the docs) as part of its use cases,

Navigation transitions as discussed in https://docs.google.com/document/d/1B1kxg6oaiDalf0f-141DMY3abNFzCQUbouiB0wO3cmU/edit was implemented in chromium and later removed, so there doesn’t appear to be an API to hook to in oxide.
