Z-буфер движка DirectX 9 не работает с D3DImage

Я пытаюсь интегрировать мой движок Direct9 в мое новое приложение WPF через D3DImage. Все работает, кроме буфера Z. С AutoDepthStencil в FALSE я могу визуализировать свои сетки, но глубина не работает. Когда я активирую AutoDepthStencil, ничего не рисуется. Я искал вокруг в течение нескольких дней и не нашел ничего, чтобы помочь meq
