Stencil test stop working when geometry shader is used

    Question

  • I use stencil test to restrict rendering of graphics objects inside a region. The works when geometry shader is set to NULL. However when I set the geometry shader, the stencil test seems to stop working. All graphics objects (both inside and outside the region) are rendered as if the stencil test is disabled. Could someone kindly tell me what's wrong.
