also in our testing the flickering has nothing to do with an Image being
displayed. The issue can be observed even with no image present, by
toggling the window fullscreen and hiding/showing the header. The header
clearly shows flicking and repainting issues in this scenario. Try the
sample app here: lp:~artmello/+junk/fullscreen_issue_header

Title:
  sdk header flickers when hide/show going in and out of fullscreen

Status in Mir:
  New
Status in ubuntu-ui-toolkit package in Ubuntu:
  New

Bug description:
  With vivid-proposed on mako.

  We have a Image component with PreserveAspectRatio set as fillMode
  filling all the Page. When the application is going fullscreen / non-
  fullscreen on device the Image flickers during the process. Hiding the
  header too seems to make the result worse. This is the scenario for
  gallery-app during media viewer.

  On this branch [0] we have a sample app that seems to trigger the
  issue. Just tap the picture to go fullscreen / non-fullscreen.
