942156 - Refine the app-to-app edge transition

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[Etienne Segonzac (:etienne)]

The current, simplistic one is here for performance reasons.

Let's try to refine it without compromising on performance.

Quick c/c from the UX meeting:
We also agreed that we need to differentiate between transitions between apps (swipe) and the current back button transition. (Currently they are the same.) To maintain performance, we're limited in the types of transitions. Etienne will experiment initially with opacity and, if that doesn't work, try a simplified drop shadow or, worst case, a slight gap between the apps. UX will work with Etienne to iterate on these transitions.

Moving this along.

We now have opacity + shadow as part of the transition with good performances.
