To avoid spreading the failure logic I think it would be cleaner to add a check in GraphicsContext3D::GraphicsContext3D and set m_private = nullptr if (!m_private->m_platformContext).

Something like changing "if (!m_private->m_surface) {" to "if (!m_private->m_surface || !m_private->m_platformContext) {" at line 398.
