      See the attached example.

      To summarise, doing the following with High DPI scaling enabled results in blurry images (bad.png):

      main.qml
      import QtQuick 2.4
import QtQuick.Window 2.2

Window {
    id: window
    visible: true

    Image {
        source: "qrc:/menu.png"
        fillMode: Image.Pad

        Rectangle {
            anchors.fill: parent
            color: "transparent"
            border.color: "darkorange"
        }
    }
}

      Taking away the fillMode: Image.Pad statement results in good.png.

      The screenshots were taken with a 4x scale factor, but I've also tested it with x2.
