Comment 8 for bug 1466510

lp:~dandrader/qtubuntu/resizeCatchUp solves the problem we have currently that by symply rotating an app from portrait to landscape (or vice-versa) you can get the app stretched. Because it didn't consume enough buffers to reach the first one with the new size that was promised on the ResizeEvent

The remaining issue is that when you press the power button to turn the display off and then again to turn it back on, MirSurfaceItem gets resized in the scene but the underlying mir surface does not get resized at all. Likely because the apps was already unfocused and getting suspended by the time the resize takes place
