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>) Signed-off-by: Olivier Fourdan <ofourdan@redhat.com> Reviewed-by: Michel Dänzer <mdaenzer@redhat.com> Acked-by: Martin Peres <martin.peres@mupuf.org> |

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
