[Interest] [Qt3D] Crash when trying to update a geometry

[Xavier Bigand]

May it come from the fact that we force Qt to use OpenGL and remove
multi-threaded scene graph?

qputenv("QML_FORCE_THREADED_RENDERER", "0");

qputenv("QML_BAD_GUI_RENDER_LOOP", "1");

qputenv("QSG_RENDER_LOOP", "basic");


QGuiApplication::setAttribute(Qt::AA_UseDesktopOpenGL, true);
