Memory leak on close

Hello,
I’m trying to port the hello_xr sample in an existing OpenGL project on Windows. I use SteamVR runtime.
I’ve merge OpenGLGraphicsPlugin & IOpenXrProgram in one class which is used with a std::shared_ptr in my application. But I have some memory leak when I close the application whereas the desctructor is called. I’ve tried to debug the closing of my class but I’ve find nothing.
Have you some ideas to debug more ? Or is a bad idea to merge OpenGLGraphicsPlugin & IOpenXrProgram in one class ?

Thanks
