Look for and relocate windows sneaking to stream target displays

When I use BetterDummy Full Screen Stream, some of my windows are spawning on the physical screen and are immediately hidden. I use Rectangle so I can use a keyboard shortcut to move it back, but I think that BetterDummy should block windows from spawning on the physical screen during full-screen streaming.

Yes, I am planning to create a background process to move Windows that somehow manage to get to the stream target display (and is covered by the stream) to the stream source display. I could take the stream target screen for exclusive use but unfortunately that blocks Mission Control (which would be annoying) in macOS so that is not a viable alternative.

Ok, thank you!

I'm also very interested in this feature. I have to fullscreen streaming since the quality is a lot better compared to mirrored. Occasionally, I have windows appearing on the physical screen which do not appear on the stream. I have to pause the streaming, move the windows and resume it.

Yes, this should be added. Note: a quicker alternative to stopping/starting the stream is just to assign a keyboard to hide/unhide the stream.
