      meta-qt5 (latest 5.9 branch and latest update to 5.11.1)

      Image, QQuickPaintedItem and maybe others are drawn opaque when they should be transparent.

      When testing the 5.9.5 RC from the meta-qt5 repository, we notice broken rendering of our QQuickWidget based application. It seems that, while z-order is preserved, Items are not transparent any more. For example, rendering a QML Image with a transparent PNG file as source will draw the background colour over previous items, instead of showing through.

      Qt 5.9.4 and before are working without issues.
