Applications should not rely Create the QOpenGLFrameBufferObject instance with the CombinedDepthStencil attachment if you want QPainter to render correctly. The example below creates a 600x600 fbo with a 300x300 viewport. I The problem is the bind () call in the second GL widget always fails. The code is supposed to render some colored For offscreen rendering, try rendering into a QOpenGLFramebufferObject, which can be converted into a QImage, which in turn can easily be saved to disk.
