The attached View3D has a Node with 2D item.
Node {
Rectangle {
width: 100
height: 100
color: hh.hovered ? "lime" : "green"
Rectangle {
anchors.centerIn: parent
width: 50
height: 50
HoverHandler { id: hh }
}
}
}
With QSG_RENDER_LOOP=threaded, the 3D scene appears to be updated even if
nothing dirty.
With QSG_RENDER_LOOP=basic, camera rotation does not apply to the scene objects.
Hover handling is also not working.
I've confirmed this is caused by update() call inside QQuick3DItem2D::updateSpatialNode().
connect(m_renderer, &QSGAbstractRenderer::sceneGraphChanged, this, &QQuick3DObject::update);
...
m_renderer->setRootNode(m_rootNode);
m_rootNode->markDirty(QSGNode::DirtyForceUpdate); // Force matrix, clip and opacity update.
m_renderer->nodeChanged(m_rootNode, QSGNode::DirtyForceUpdate); // Force render list update.
nodeChanged() emits sceneGraphChanged(), which schedules update.
I'll send patches later.
