I think there is an API (that was added with sidecar) to create a virtual display. So at best you could retrieve the framebuffer and then display that. I don't think there is an easy exposed way to get per-window information, aside from doing a screencapture (which likely would not work if you also wanted to hide the window).

Interesting… do you have a link to the docs? The easiest thing prob would be to set the window to be fullscreen, but on that virtual display. That would accomplish per window screen capture.

It's a private API CGVirtualDisplay, but mostly well reverse engineered. Here's one example I found of a wrapper library
