      Calling QWindow::show() may remove a hint from the _NET_WM_STATE window property previously set by the programmer. The reason for this is that QXcbWindow::setNetWmStates ignores hints not supported by Qt (i.e. sticky).

      This is a regression from Qt 4, which declares in dist/changes-4.3.1:

      QWidget now merges any existing _NET_WM_STATE property together with its own state.
