Thanks for the follow-up.
I am not sure re; EL9 and testing against X11/Wayland.
There are some kernel logs showing where the segfault and kernel traps
occur and also some gdb crashdump analyses with stacks shown at the github
link below. The crashes I saw were all in the desktop components and not
in x2goagent/nxagent.

Most probable all those desktops require features that are not offered by NX.
We have seen many cases where they do not correctly check what versions of x
server extensions are available and assume higher versions. I am not sure but
maybe EL9 apps are only tested
against Wayland and not longer X11?
Do you have more details when they crash? Will the DEs crash or the
x2goagent/nxagent?

I originally submitted a detailed bug report at the Mate Desktop issues
Github page here https://github.com/mate-desktop/mate-desktop/issues/553.
I subsequently discovered that other desktops are similarly affected. All
of them experienced segfaults or kernel traps in parts of their
components, particularly in the Marco window manager that Mate uses.
I have also tried Gnome, Kde, xfce, Cinnamon & Icewm desktops, again on a
Centos Stream 9 system. Similar results were found on an Alma 9 system so
I do not believe the problem is specific to the 'upstream' / lesser-tested
nature of CS9.
Apart from Icewm which remained usable even with the segfaults, the other
desktops (particularly Mate which we use a lot for remote working) are
rendered unusable by this problem. None of our Centos 7 systems have this
problem.
I am running out of ideas to diagnose/fix this problem.
Any thoughts?
Thanks
