Xwayland uses an output serial number it increments each time a new Wayland output is added. On server regeneration, that static value is not cleared, and therfore the output numbers keep increasing each time the Xserver restarts. To avoid that issue, make the output serial part of the xwl_screen, which gets recreated on server regeneration, so that index is reset to 0 automatically on server regeneration.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
