@alive any idea what's going on?

Might be cards view (task manager issue) because the black overlay should appear soon before seeing homescreen opening animation.

I don't see this in my unagi though :/

It seems this is not reproducible on ICS based devices like Unagi. I reproduced it on a kitkat device. It may also be reproducible on a Jellybean device like nexus 4.

When we go to the cards view, we actually go to the homescreen first, then show the cards view. The cards view dom elements required for it to function are all in the homescreen / system application so there is no way around this right now. We could possibly ensure that the homescreen / system application has the black overlay enabled before we transition to it... not sure if that will solve the problem though.

Alive, what do you think?

Works for me, just call homescreenWindow.fadeoOut and homescreenWindow.fadeIn when cardsView is shown / hidden.

This wasn't a problem in v1.3 on the same device. Any idea what changed?

:diego, many things have changed around window management, any of them could be causing this.

:preeti, it's already assigned and should land within this spring which ends 3/28, I can't guarantee it for the 21st.

apologies for the typo, that should read "sprint" not "spring".

Yep, I'm stuck on another bug so I'm going to be taking care of this today.

Pull Request - Added 'cardviewbeforeshow' and 'cardviewbeforeclose'. Made HomescreenLauncher use those new events to fadeOut/fadeIn the Homescreen instance when appropriate.

No need for approval. it's already 1.4+

Neat side effect, it feels more responsive. :)
