[Bug 1328839] Re: Toggling fullscreen causes wrong window behaviour

 

We've not tested QtMir/Unity8 handling an app changing to fullscreen and
then back to normal, so that needs to be done.

Also need to check qtubuntu allows a client app to ask for fullscreen
and back again to normal.

  Toggling fullscreen causes wrong window behaviour

Bug description:
  I’m implementing fullscreen mode for the browser application, and I’m
  seeing two issues, which can be reliably reproduced with the following
  piece of QML:

  import QtQuick 2.0
  import QtQuick.Window 2.1
  import Ubuntu.Components 0.1
  Window {
    id: window
    Button {
      anchors.centerIn: parent
      text: "toggle fullscreen"
      onClicked: window.visibility = (window.visibility == Window.FullScreen ? Window.AutomaticVisibility : Window.FullScreen)
    }
  }

  Issue #1: when toggling fullscreen on, the top panel is hidden as
  expected, and consequently the coordinates of the window change on
  screen, but the contents of the window are not redrawn, so in the
  example above tapping the button has no effect (one needs to tap
  slightly above it to activate it)

  Issue #2: when toggling fullscreen off, the top panel is not restored.
