Since the kernel update to 5.15.0-47, all my virtualbox VMs had become barely usable. In all my Ubuntu guests, gnome-shell or compiz would crash quite often.
I installed the virtualbox update (6.1.38-dfsg-3~ubuntu1.22.04.1) from jammy-proposed, and I can confirm the problem is resolved. My VMs are now working normally, no more inopportune crashes in the guests.
