snprintf doesn't terminate the string if it truncates, so things like
this are lurking crashers:
../hw/dmx/dmxprop.c: In function ‘dmxPropertyIdentifier.part.0’:
../hw/dmx/dmxprop.c:94:36: warning: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size 123 [-Wformat-truncation=]
snprintf(buf, sizeof(buf), "%s:%s:%s", DMX_IDENT, hostname, display);
^~ ~~~~~~~~
../hw/dmx/dmxprop.c:94:5: note: ‘snprintf’ output 7 or more bytes (assuming 262) into a destination of size 128
snprintf(buf, sizeof(buf), "%s:%s:%s", DMX_IDENT, hostname, display);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../hw/dmx/dmxprop.c: In function ‘dmxPropertyWindow’:
../hw/dmx/dmxprop.c:372:36: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size between 0 and 127 [-Wformat-truncation=]
snprintf(buf, sizeof(buf), "%s,%d", id, dmxScreen->index);
^~
../hw/dmx/dmxprop.c:372:5: note: ‘snprintf’ output between 3 and 140 bytes into a destination of size 128
snprintf(buf, sizeof(buf), "%s,%d", id, dmxScreen->index);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We could be more precise about termination, but meh.

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
