Question / Help Recording dual screens

I'd like to be able to record two monitors.

What's going on: Recording a browser game, but the CSS layout is really bad. To be able to play it, I need to have my two monitors "Stacked vertically" in system preferences, and the browser window spread over both monitors.

I can do that. It's not great -- there's a number of things that can trigger the window to collapse to only one monitor, and then it takes time and effort to resize it back.

Options that I see:
1. Window recording. But not only is this normally slow, I can't help but think it will be even slower with a split screen window.
And, I don't know what happens if a 1024 wide, 720 + 636-ish tall window suddenly collapses down to 1024x720, or if I need to shrink it to thin to get it down tall and then back to full -- how does the recording handle this?

2. Two different OBS's running, each recording a different screen.

3. ???
4. Profit.

Is there a better way?

Window recording is non-performant on MacOS.

Try using Display and then cropping to a window. However, if the window collapses, or is closed or minimized, OBS will stop seeing it-- it'll just go black.

Running two OBS processes is most likely not going to work. I used to be able to do this with different versions (one 17.x, one 18 or 19.x) but whatever 20.x is doing to the preferences files the old versions don't like-- they crash on startup.
