At creation, Xwayland uses a generic output name ("XWAYLAND0", etc.) for
the XRandR outputs, and later, once the name is known from the Wayland
protocols, updates the output names using the actual names from the
Wayland compositor.
However, when doing so, it simply updates the string, the "nameLength"
isn't updated, so the name passed to the clients might either end up
being truncated or contain portions of the previous (initial) output
name.
Note, this is using a fixed size buffer initialized with zeros, so this
cannot leak any data other than the previous output name, so this is
mainly a cosmetic issue.
Update the output's "nameLength" when updating the output name.

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.
