Problem is that the Lockscreen height is defined like this:

    Lockscreen {
        y: panel.panelHeight
        width: parent.width
        height: parent.height - panel.panelHeight
    }

and Lockscreen contains:

    Image {
        // Limit how much memory we'll reserve for this image
        sourceSize.height: height
        sourceSize.width: width
        fillMode: Image.PreserveAspectCrop
    }

panel.panelHeight is a property which is animated during unlock, if the
application is fullscreen. Animating sourceSize is a bad thing, as it
causes the CPU to rescaling the image each time.

Title:
  Unlocking the phone over fullscreen app is very slow

Status in unity8 package in Ubuntu:
  In Progress

Bug description:
  Steps to repro:
  * have a pass{code,word}-protected phone
  * start dialer
  * lock the phone
  * unlock the phone

  Expected:
  * nothing much, stuff unlocks fluently and all

  Current:
  * fade out of the lockscreen takes like 2-3s, dialer and panel seem to fight over fullscreen vs. maximized surface size
