DirectX11 COM对象0引用未发布

Question

我试图追查“内存泄漏”。然而这似乎并不像一个真正的内存泄漏，因为调用ReportLiveDeviceObjects报道，有0引用

D3D11 WARNING: Live ID3D11Texture2D at 0x00000140D3FE44F0, Refcount: 0, IntRef: 1 [ STATE_CREATION WARNING #425: LIVE_TEXTURE2D] 
D3D11 WARNING: Live ID3D11RenderTargetView at 0x00000140D3FCBB60, Refcount: 0, IntRef: 0 [ STATE_CREATION WARNING #428: LIVE_RENDERTARGETVIEW] 
D3D11 WARNING: Live ID3D11Texture2D at 0x00000140D3FE5BF0, Refcount: 0, IntRef: 1 [ STATE_CREATION WARNING #425: LIVE_TEXTURE2D]

正如你所看到的，ID3D11RenderTargetView对象既有0内部和外部参考。但它仍然是一个活的对象。什么可能导致这种情况发生？

为了清楚起见，我用这通过SharpDX，虽然这应该不会影响从11 DirectX的输出

DirectX 11的使用资源的“递延毁灭”，所以通常如果你需要强制销毁你需要Flush。例如，在Direct3D game templates，你需要完全取消绑定并摧毁调整前的渲染目标：

// Remove any bound render target or depth/stencil buffer 
ID3D11RenderTargetView* nullViews [] = { nullptr }; 
m_d3dContext->OMSetRenderTargets(_countof(nullViews), nullViews, nullptr); 

// Destroy the views (which themselves hold the references to the resources) 
m_renderTargetView.Reset(); 
m_depthStencilView.Reset(); 

// Flush the immediate context to force cleanup 
m_d3dContext->Flush();
