On a fresh Ubuntu 24.04.3 ARM64, DemoRunner built with latest tip on master crashes at startup and seems to even crash the current graphic session.

This is caused by a bug in Gnome afaik, where the Wayland session doesn’t correctly integrate X11 system-tray icons (or at least, some part of the X protocol that seems to work correctly under a fully X11 session). It’s not ideal that it crashes the entire desktop; perhaps we should attempt to avoid creating the system tray icon entirely when we detect a Wayland session.
There’s more info here:

We’ve now added a workaround to avoid crashing the desktop session on Ubuntu:
committed 11:29AM - 08 Jan 26 UTC
The Ubuntu Wayland session crashes completely when adding a system tray
componen… t. This is difficult for us to debug (because the desktop goes
away taking our debug session with it!), so this change just disables
the system tray component on affected platforms.
