Huge memory leak on wglDXLockObjectsNV/wglDXUnlockObjectsNV when a texture retrieving.

Has anyone encountered this problem?
In my case it is observed on GTX 880M with latest drivers.

Yes this is a bug in the NVIDIA driver. It does not always appear. In my case, I cannot see it with Windows process monitor or with leak checking. But for some systems there is a huge leak as you have discovered.

Malcolm Bechard has been communicating with NVIDIA and it appears that they have fixed the problem and a driver with the bug fixed may be released very soon.

Meanwhile we cannot use DirectX 11 for the GL/DX interop functions apart from testing, and that is why I restored the option for DirectX 9 within the SDK. By using "SetDX9(true)" within your app, all the interop functions will use DirectX 9 instead of DirectX 11 and the app will be 100% compatible with existing Spout apps.

Had the same issue with drivers from end 2013, but updating the nvidia drivers fixed it.

So this isn't an issue with latest NVidia drivers? if so then close the issue?

OK.
