Picom and Zoom

Ever wondered why zoom has an optional dependency on picom in the Arch User Repository (AUR)? It says

extra compositor needed by some window managers for screen sharing

If only I had actually bothered to read this at some point, because then I wouldn’t have had to wonder why Zoom whiteboards wouldn’t work for me when inside a bspwm session (tiling window manager without a compositor). If I start picom together with bspwm everything works just fine. TIL.
