Valve’s nested compositor, and the thing running underneath Steam Deck’s game mode. For streaming, its value is making a game’s window behave predictably: it renders at a resolution you choose and presents a single stable surface.

That helps with capture, especially for games that change resolution on startup or misbehave when a compositor changes underneath them. Combining it with obs-vkcapture is a common way to get reliable game capture on Wayland.
