I am observing the following phenomenon on Windows 10:

when rendering realtime content to an output window [jit.window] and changing focus to a different application, a lag to the output is introduced. It is about 40ms, so barely visible in most use cases, but for projected augmented reality applications this huge. I can observe this because of the use of a high performance tracking system:

1. the video below shows at the beginning the latency as it should be, 

2. then I select another app (in this case file-explorer) - see the latency increase.

3. simply setting the focus back to Max is not fixing it.

4. I have to switch off and on the [jit.window] context that renders the final output to the projectors to get back to the same latency as at the beginning.

the same effect happens when I switch on @vsync on the the above [jit.window] context. the only way to get back to low latency is to switch off/on the context.
