I run Zoom from flatpak, which runs it in a container, and sandboxes it to some extent [1]

This probably explains why, when i try to screenshare a single application window, not every application shows up! I can share my browser, file manager, and various other things, but not windows for games started by Steam.

Are you using Wayland? That might be an artifact of Steam and games running via XWayland.

As far as i know, no, it's all still pure X11. I would like to try Wayland, but i'm using Cinnamon as a desktop, and i'm not sure they work together.

Games always seem impacted in odd ways by remote desktop protocols. One game might run fine, while another is just a black screen, or an uncontrollable mouse.

It makes me wonder how Things like Steam streaming and Paperspace get around the issue.
