[Blocking Requested - why for this release]: nominating this as a blocker, Slow app transition and white screen causes poor UX. Also this is a regression

Blocking Reason: Regression and bad user experience (white screen)

Punam, please investigate Thanks Hema

Attaching PR which updates body background-color to #0E1214. Setting background-color explicitly fixes the white screen seen while opening Video app. Device used: Flame-KK 319 mb BuildId:20140929040202 OS ver: 2.2 Hub, I am asking you to review the attached patch as you are familiar with bug 1054105 where we removed background-color as part of simplifying layers. Please review. Thanks

I have tested the attached patch for white screen seen on opening video app. I wasn't able to replicate white screen seen on tapping camera icon on my Flame, setting NI flag for Petes to help test and confirm if attached patch fixes the white screen seen on tapping camera icon inside video app. Thanks

This is a dupe of bug 1069272. Will mark the other as dupe. I was about to submit this fix.

Comment on attachment 8497045 [details] PR with fix for bug 1072013 I'm not peer to review this. But I did f+. This is the fix I was about to submit for bug 1069272 which I have new duped with this bug. John Hu should be able to review. Thank you kindly.

I have tested it on 2.2 kit kat base and can be easily uplifted to 2.1. Thanks

This issue does not reproduce on the attached patch with the Flame 2.2 KitKat Base (319mb).

A quick note: to reproduce you must disable the lock screen (as the video shows) and wait 2-3 seconds before suspend a resume

Comment on attachment 8497045 [details] PR with fix for bug 1072013 This looks good. Hubert Should we reopen the bug 1054105? This PR looks like a revert of patch of bug 1054105. But the difference is this PR puts background color in body instead of in html, body. I don't know if there is any difference in Graphics but the outcome is identical to Gaia.

No I don't think we need to reopen bug 1054105. This was an alternative to the style change done there.

[Risk to taking this patch] (and alternatives if risky): not many. Alternative is just reverting bug 1054105 altogether. [String changes made]: none.
