Hang when interacting with desktop icons on X11

[Emanuele]

It's easy to reproduce: Put files on the desktop, select them, the selection remains and the whole shell crashes.
I switch to a tty2 session and see the gnome-shell process with 100% CPU.

I also played it on VM: https://youtu.be/knTm-WYdT6Y

I tried to start a session with "ubuntu wayland" on the VM and the problem is not there, the problem is only on the xorg session.
I can't start "ubuntu wayland" on the host desktop with the NVIDIA GPU, of course I enable "nvidia-drm.modeset = 1", but that's another problem.
