There've been reports downstream of Xwayland segfaulting in the function
xwl_present_execute() because xwl_window_get_damage_region() returned an
invalid pointer:
#10 RegionUninit at ../include/regionstr.h:165
#11 RegionEmpty at ../include/regionstr.h:194
#12 xwl_present_execute at ../hw/xwayland/xwayland-present.c:1138
#13 xwl_present_pixmap at ../hw/xwayland/xwayland-present.c:1274
#14 present_pixmap at ../present/present.c:249
#15 proc_present_pixmap_common at ../present/present_request.c:166
#16 proc_present_pixmap at ../present/present_request.c:186
#17 Dispatch at ../dix/dispatch.c:550
#18 dix_main at ../dix/main.c:277
The most likely reason for this is that window_get_damage() returned
NULL, which might happen if xwl_window_update_surface_window() didn't
call register_damage().
To avoid that issue, move the call to register_damage() back to
xwl_realize_window before calling ensure_surface_for_window().

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.
For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
