Is there a program (maybe a compositor) that can display a window in 2 windows? (lemmy.world)

Context: Windows on Niri doesn't span across monitors, and the dev doesn't seem very interested in adding this feature (https://github.com/YaLTeR/niri/issues/2309)

I am trying to setup Flameshot on Niri. While Flameshot's window spawns with the full 2-monitor dimensions, it can only appear on one screen due to the limitation of Niri. I currently have a temporary-solution script where I position the window differently based on which monitor my cursor is on.

Is there a way I can split the Flameshot window in 2 so it can appear on both screens? I don't know if there exists some kiosk compositors like cage that does this.

So you want something that spans across two monitors? doesn't Plasma do this?

I'm using the Niri window manager
