    Description

      In QTBUG-44171 it was noted, that SVG images look pixelated when used on a HiDPI screen. The same is true for PNG images:

      Image {
    source: "https://upload.wikimedia.org/wikipedia/de/b/bb/Png-logo.png"
    sourceSize.width: 32
    sourceSize.height: 32
}

      This will result in pixelated image for larger QT_SCALE_FACTORs.
