It seems that the Intel(R) RealSense(TM) SDK Privacy Notification application causes some issues with the depth stream of the camera.
I experience a big lag in the depth stream when the privacy notification is running. If I close the privacy notification program, the application runs fine. On the other hand, the color stream is not affected by this, as it runs fine in both cases.
Checking further, it seems that there are some permissions issues. For some reason, only the color camera access is requested, so the Privacy Notification app delays or ignores the access for the other streams.
For now, I just don't use the Privacy Notification app, but this means that the apps will not work on other PC that is running the privacy app.
How can I enable all the streams to pass through the Privacy Notification app?
