The window buffer mechanism would free the pixmap and its corresponding
Wayland buffer as soon as window buffers are disposed.
Typically when the X11 window is unrealized, the current window buffer
is still used by the Wayland compositor and yet Xwayland will destroy
the buffer.
As a matter of fact, Xwayland should not destroy the Wayland buffer
before the wl_buffer.release event is received.
Add a reference counter to the window buffer similar to the to pixmap
reference counter to keep the buffer around until the release callback
is received.
Increase that reference counter on the buffer which will be attached to
the surface, and drop that reference when receiving the release callback
notification.
v2: Use a specific reference counter on the buffer rather than relying
on the pixmap refcnt (Michel Dänzer <mdaenzer@redhat.com>)

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.
