Re-map the SELinux security classes on policy loads, as the mapping will
be desynchronized (see man:selinux_set_mapping(3)) and audit messages
will not show the actual class and permission names:
USER_AVC pid=24283 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:xorg_t:s0 msg='avc: denied { 0x10 } for request=XFIXES:SelectSelectionInput comm=/usr/bin/python3 resid=6400001 restype=WINDOW scontext=xuser_u:xuser_r:systemd_user_instance_generic_bin_t:s0 tcontext=xuser_u:object_r:xorg_t:s0 tclass=(null) permissive=1
In addition use type-safe assignments.

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.
