DirectX: Leaked memory released on App Suspend

Question

I have a DirectX application which seems to leak a few objects during its several runs (after opening and closing page SwapChainBackgroundPanel).

The interesting thing is that these DirectX objects seem to be somehow released if the app is suspended via Visual Studio. What might be releasing the resources? I am asking this since I would like to do it myself to release the memory without needing App suspension.

Below are the DirectX objects remain allocated after page close but deallocated with App Suspension.

Hi,

How did you get the memory leak information? From Visual Studio or other tools?

Best regards,
Jesse

Hi,

I am getting the memory leak info from the Task Manager. Object destroy logs are output from DirectX Debug Layer which is activated with DirectX Control Panel.
