在Windows 8上使用OpenGL时出现DXGI警告？

Question

我正在使用OpenGL(而不是DirectX)编写CAD应用程序.在Windows 8 Pro(64位)上运行调试版本时,在应用程序正确终止之前,会将以下消息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,产生以下消息:

在Windows Vista及更高版本中,DirectX和OpenGL实际上都可以通过DXGI工作.DXGI管理设备.使用的实际渲染API(OpenGL/DirectX)producer在DXGI中称为a ,因此我们可以安全地假设该消息与您的通用OpenGL用法有关.

因为它抱怨生产者和参考数量为2的活对象,你可能没有正确地破坏你的OpenGL上下文吗？(即成功呼叫wglMakeCurrent( NULL )和wglDeleteContext)这样的省略根本不是一个实际问题,因为在处理终止时都会被破坏,但是需要警告.
