Thank you Qt for quietly fixing a bug in MonthGrid and ruining everything ;-)

So lets say you have the following QML code:

import QtQuick
import QtQuick.Layouts
import QtQuick.Controls

ApplicationWindow {
    visible: true
    width: 320
    height: 240
    property var myDate: new Date();
    MonthGrid {
        anchors.fill: parent
        id: monthGrid
        locale: Qt.locale("en_US")
        Layout.fillWidth: true
        month: myDate.getMonth();
        year: myDate.getFullYear();

        delegate: Label {
            horizontalAlignment: Text.AlignHCenter
            verticalAlignment: Text.AlignVCenter
            enabled: model.month === myDate.getMonth()
            text: model.day
            Rectangle {
                anchors.fill: parent
                color: "blue"
                opacity: .5
                radius: 100
                visible: (model.month === myDate.getMonth()) &&
                         (model.day === myDate.getDate())

            }
        }

        onClicked: function(getDate) {
            console.debug(getDate);
            myDate = getDate;
        }
    }

}

You run it on Qt 6.9 or later. It works fine. Great! But run it on Qt 6.8 or older (including 5.15), you will notice the clicked date will always be off by one. Why? Because there was a bug in the MonthGrid's onClicked function that would give the wrong date. So they fixed it. Great, right? No! So you now need a different version of the code for Kubuntu 25.04 (or Debian 13) vs. 25.10! And it's not that easy to figure out if you got the 6.9 fix or not. Now I have to decide if I want to support Debian or not.

Thanks Qt, for ruining everything!!! (/s)

My current workaround, lol:

        onClicked: function(getDate) {
            if(getDate.getHours() > 0) {
                myDate = new Date(getDate.getFullYear(),
                                  getDate.getMonth(),
                                  getDate.getDate() +1);
            }
            else {
                myDate = getDate
            }
