This is because QML by default applies the opacity on all children
separately, to have a blended texture you need to enable layering on it:

http://qt-project.org/doc/qt-5/qml-qtquick-item.html#layer.enabled-prop

Problem with that is that it's more expensive because the texture has to
be rendered offscreen first. Wonder if we can make the root app surface
invisible when prompt is fully on? Or do we support/expect
semitransparent prompts?

Title:
  Can see through prompt surface when entering spread mode

Status in “unity8” package in Ubuntu:
  Triaged

Bug description:
  Steps to reproduce the issue:

  1 - Make sure you don't have an Ubuntu One account set up.
  2 - Launch settings
  3 - Tap on "Accounts" icon
  4 - Tap on "Ubuntu One" row
  5 - Wait for the "Sign in to your Ubuntu One account" prompt to show up
  6 - Start a right-edge drag slowly

  While the "Sign in to your Ubuntu One account" starts moving to the
  left and dash coming in from the right, you can see the "Accounts"
  root page behind the "Sign in to your Ubuntu One account" one.

  What seems to be happening is that both the app surface and the prompt
  surface get their opacities reduced, so both get translucent. The end
  result being a blending of the black pixels from the PhoneStage
  background, the "Accounts" app surface and the "Sign in" prompt
  surface.
