Mihaill

Hi!

I use Win 10, MinGW 64, Qt 6.2.3
Why my app not work?

QT += quick core multimedia datavisualization

import QtQuick
import QtQuick.Layouts
import QtQuick.Controls
import QtDataVisualization 1.2

Item {
    width: 1000
    height: 700

    Label {
        text: "test label 3D"
        font.pixelSize: 50
        z: 2
    }
    Surface3D {  // or     Scatter3D {
    }
}

In console I have only:

NVD3DREL: 
GR-805 : DX9 Overlay is DISABLED
NVD3DREL: GR-805 : DX9 Overlay is DISABLED

In main.cpp need add

qputenv("QSG_RHI_BACKEND", "opengl");

more code:

#include <QtDataVisualization/qutils.h>
//! [2]

#include <QtGui/QGuiApplication>
#include <QtCore/QDir>
#include <QtQml/QQmlContext>
#include <QtQuick/QQuickView>
#include <QtQml/QQmlEngine>

int main(int argc, char *argv[])
{
    qputenv("QSG_RHI_BACKEND", "opengl");
