On: DeskPad – A virtual monitor for screen sharing

[delusional]

What an intriguing idea. I wonder if I could do something similar on linux by placing a second monitor on top of my current one with xrandr.

On Linux, you can try Xephyr (https://www.freedesktop.org/wiki/Software/Xephyr/, https://wiki.archlinux.org/title/Xephyr). It's not as nice as DeskPad, but you can basically achieve the same thing.

Xephyr runs a whole new X server - it's not as easy to drag and drop an application into the nested server, it has to be launched with DISPLAY=:1.

It's too easy to just use OBS for this, in my opinion. Add the pipewire display capture, add a filter to crop it to a corner, stretch that container to fit the stage, open the window in the corner. Fairly simple.
