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().
