Code below leads to SIGSEGV in case m_gl of QSGDefaultRenderContext is null:
if (m_context->openglContext()->format().profile() == QSurfaceFormat::CoreProfile) { m_vao = new QOpenGLVertexArrayObject(this); m_vao->create(); }
It is unfortunately not possible to provide steps or minimalistic code sample
