I'm testing Quick3D on Android, all good, but if I use a skybox the performance
is really bad or does not work at all.
The following test project with trivial code is just a skybox and a red
cilinder.

Runs fine in desktop linux mint, windows, MacOS, iPhone, but in my 2 android
devices:
- tablet Lenovo Tab M10 TB-X306F, OS Android 11, when I run the program, I get
a black screen, it takes 55 seconds to load the image of the skybox and the red
cylinder
- mobile nokia 5.4 OS Android 10: compilation fails with the following errors:

It seems that skybox uses an extension that is not available in nokia 5.4 GPU
or software.I will report a bug, but before that, maybe someone wants to give
theirs 2 cents ?
The code is
Window { visible: true width: 640 height: 480 title: qsTr("Hello
World")
View3D { id: view3D visible: true width: parent.width
height: parent.height
//SkyBox mode environment: SceneEnvironment {
backgroundMode: SceneEnvironment.SkyBox lightProbe: Texture {
source: "qrc:/galaxy.hdr" mappingMode:
Texture.LightProbe } }
// color mode /*environment: SceneEnvironment {
backgroundMode: SceneEnvironment.Color clearColor: "skyblue"
}*/
//! [camera] PerspectiveCamera { id: cam
position: Qt.vector3d(0, 0, 500) } //! [camera]
DirectionalLight { eulerRotation.x: -45 }
Model { id: ball //source: "#Cylinder"
source: "#Cylinder" scale: Qt.vector3d(1, 1, 1)
materials: [ DefaultMaterial { diffuseColor: "red"
} ] position: Qt.vector3d(-100, -150, 0)
onPositionChanged: console.log(position) } }}
