Quick3D does not work with OpenGL backend on macOS

When running Quick3D examples on macOS with OpenGL backend then this debug message is shown and nothing is drawn:

Particles not supported due to missing RGBA32F and RGBA16F texture format support
No GLSL shader code found (versions tried:  QList(120) ) in baked shader QShader(stage=0 shaders=QList(ShaderKey(1 Version(130 QFlags()) 0)) desc.isValid=true)

Steps to reproduce:

1. Open customeffect example.
2. Add "qputenv("QSG_RHI_BACKEND", "opengl");" to main.cpp
3. Comment out // QSurfaceFormat::setDefaultFormat(QQuick3D::idealSurfaceFormat()); in main.cpp

On other platforms (iOS, Windows) it works fine.
