opengl - 在 Windows 8 上使用 OpenGL 时出现 DXGI 警告？

Question

我正在使用 OpenGL(不是 DirectX)编写 CAD 应用程序。在 Windows 8 Pro(64 位)上运行调试版本时，以下消息会在应用程序正确终止之前打印到调试器的控制台窗口:

DXGI WARNING: Process is terminating. Using simple reporting. Please call ReportLiveObjects() at runtime for standard reporting. [ STATE_CREATION WARNING #0: ]
DXGI WARNING: Live Producer at 0x0000009E51808AD8, Refcount: 2. [ STATE_CREATION WARNING #0: ]
DXGI WARNING:   Live Object at 0x0000009E5180A570, Refcount: 2. [ STATE_CREATION WARNING #0: ]
DXGI WARNING: Live                         Object :      1 [ STATE_CREATION WARNING #0: ]

我不知道这是从哪里来的。 DXGI 似乎与 DirectX 有关，我没有使用它。任何提示？

更新

按照 Paul-Jan 的建议，我启用了设备调试，这会产生以下消息:

在 Windows Vista 及更高版本中，DirectX 和 OpenGL 实际上都通过 DXGI 工作。 DXGI 管理设备。实际使用的渲染 API(OpenGL/DirectX)称为 producer在 DXGI 中，所以我们可以放心地假设该消息是关于您的通用 OpenGL 使用的。

当它提示生产者和事件对象的引用计数均为 2 时，您是否没有正确破坏 OpenGL 上下文？ (即成功调用 wglMakeCurrent( NULL ) 和 wglDeleteContext )这样的遗漏根本不是一个实际问题，因为两者都在进程终止时被隐式销毁，但需要警告。
