Hi all, On my Qt Creator 10 (Qt 6.5) and Windows 10 x64 I'm running this example as my first 3D project. So created a new QtQuick project and wrote this: import QtQuick import QtQuick.Controls import QtQuick.Window import QtDataVisualization ApplicationWindow { width: 640 height: 480 visible: true title: qsTr("Hello World") Item { width: 640 height: 480 Bars3D { width: parent.width height: parent.height Bar3DSeries { itemLabelFormat: "@colLabel, @rowLabel: @valueLabel" ItemModelBarDataProxy { itemModel: dataModel // Mapping model roles to bar series rows, columns, and values. rowRole: "year" columnRole: "city" valueRole: "expenses" } } } ListModel { id: dataModel ListElement{ year: "2012"; city: "Oulu"; expenses: "4200"; } ListElement{ year: "2012"; city: "Rauma"; expenses: "2100"; } ListElement{ year: "2012"; city: "Helsinki"; expenses: "7040"; } ListElement{ year: "2012"; city: "Tampere"; expenses: "4330"; } ListElement{ year: "2013"; city: "Oulu"; expenses: "3960"; } ListElement{ year: "2013"; city: "Rauma"; expenses: "1990"; } ListElement{ year: "2013"; city: "Helsinki"; expenses: "7230"; } ListElement{ year: "2013"; city: "Tampere"; expenses: "4650"; } } } } The program shows nothing and the Application Output window, it writes: ... crashes , and in the Compile Output window, it writes ninja: no work to do. And when I press F5 to start debugging to see the problem, I get this: What is the problem and how to solve it, please?

Qt Creator shows nothing for my first 3D project!

Yes, using a Window instead of that Item solved the issue.
```
import QtQuick
import QtQuick.Window
import QtDataVisualization

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Item {
        width: 640
        height: 480

        Bars3D {
// ...
```
I get this output:

And when I move the mouse holding the right-click button, it shows different views of that, like:

Do you get the output with the same quality?
(If possible send a screenshot of the output once you run the project, please. I just like to be sure about my graphics card performance for that project)
