Add full screen window mode for streaming to prevent windows sneaking under the stream target (experimental)

[3DCoded]

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.

I added a "Full Screen Window Mode" option that should put the target display into full screen window mode, which should stop windows sneaking in (also prevents dragging windows in). But it is not working perfectly well so I consider it experimental. The option will only appear when the user holds the OPTION button while opening the Screen Stream menu.

Will probably look for other ways - it is possible to enumerate Windows but moving foreign app windows is somewhat problematic - although can be done through the Accessibility API (AXUIElement).
