This warning is probably a false alarm, but it's trivial to fix.
| ../glx/createcontext.c: In function ‘__glXDisp_CreateContextAttribsARB’:
| ../glx/createcontext.c:172:24: warning: dereference of NULL ‘0’ [CWE-476] [-Wanalyzer-null-dereference]
| 172 | switch (attribs[i * 2]) {
| | ~~~~~~~^~~~~~~
The situation is too complex for the analyzer to handle:
(but also not immediately clear for the human reader)
* `attribs` is only NULL when req->numAttribs is 0
* in that case, the for loop is no-op, so `attribs` won't ever be deref'ed.
We can make it easier for both analyzer as well as human reader by just putting
the whole loop into an `if (req->numAttribs)` and assigning it inside there.
There shouldn't be any (practically measurable) extra cost.

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
