You don't need exclusive fullscreen on Windows to bypass the compositor. Fullscreen borderless windows also bypass the compositor. And in newer Windows versions the compositor can be bypassed even in regular windows using hardware overlays.

Windows's desktop compositor DWM is actually very advanced, and I don't believe any Linux desktop compositor is anywhere close. It's one of the things I miss when leaving Windows.

Very cool! Yeah I love borderless fullscreen mode, its very convenient.
