Text's underline thickness is unstable on fractional screen's scale factors

XMLWordPrintable

      Text's underline thickness is unstable on fractional screen's scale factors.
      Reproduced at least on 125% screen's scale factor.

      import QtQuick 2
import QtQuick.Window 2

Window {
    width: 640
    height: 480
    visible: true

    ListView {
        anchors.fill: parent
        model: 100
        delegate: Text {
            text: "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s..."
            font.pixelSize: 16 // not reproduced on 12, 15, 18, 21, etc
            font.underline: true
            renderType: Text.NativeRendering // reproduced on Text.QtRendering as well
        }
    }
}

      Pay attention that to reproduce this on Qt 5 you need call

      QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication::setHighDpiScaleFactorRoundingPolicy(Qt::HighDpiScaleFactorRoundingPolicy::PassThrough);

      before creation of the application object
