- Wayland only. X11 is not supported.
- Full overlay behavior requires layer-shell. Known-good layer-shell targets include Hyprland,
Sway, River, Wayfire, Niri/COSMIC, and KDE Plasma/KWin.
- GNOME uses the xdg-shell/portal fallback, so some fullscreen and input behavior differs.
- Light passthrough requires layer-shell. It is disabled on the xdg-shell fallback because keyboard passthrough cannot be made reliable there.
- Some compositors handle fullscreen or input differently.
- Capture shortcuts need external tools for best results (see Installation → Build from source if you are not using packages).
