Unsolved Software rendering in QQuickItem/QSGGeometryNode

[posix]

I'm trying to draw a colored square in my custom QML component (QQuickItem).

QQuickItem::updatePaintNode similar code:

QSGGeometryNode *rect = new QSGGeometryNode();
QSGFlatColorMaterial *material = new QSGFlatColorMaterial();
QSGGeometry *geometry = new QSGGeometry(QSGGeometry::defaultAttributes_Point2D(), 4);

QSGGeometry::updateRectGeometry(geometry, boundingRect());
material->setColor(QColor::red);

rect->setMaterial(material);
rect->setGeometry(geometry);

I'm using software rendering like this:

QQuickWindow::setGraphicsApi(QSGRendererInterface::Software);

The problem is that the square is not drawn. If I turn on GPU rendering (OpenGL or Vulcan), then it works and I see a square. I am using Qt 6.6.0 from MaintenanceTool.

How to fix it?
