    Description

      If SVG icons are used in a QAbstractItemModel for Qt::DecorationRole then the icons are rendered pixelated if QT_SCALE_FACTOR > 1 (e.g. 1.25 or 1.5). The SVG icons are rendered properly if QT_SCALE_FACTOR is 2. The attached project shows the issue. If a pixmap is used instead of a SVG image, the decoration icons are properly rendered. Start the application with the included StartHighDpiFixed_150.bat file to see the issue.
