Description
Qt's 3D performance is far lower than our competitors.
It is almost caused by FBO bliting.
Scene3D needs to use FBO to mix the scene in QtQuick.
Usually, however, 3D scene is rendered on top or background layer.
Scene3D doesn't need to use FBO in this case.
We can improve Qt3D's performance if we have FBO-less Scene3D for most of the cases.
