Major update
--------------
I've discovered that by switching to the open source Nouveau display driver the problem disappears, even with the newest Ubuntu 5.13.0-20 kernel.
The problem was related to the "nvidia-driver-470" for my video card: GM107M [GeForce GTX 950M].
The older 5.11.0-37 Ubuntu did not had this problem, because simply there were no Nvidia drivers built by DKMS for it. Probably, I switched to the Nvidia proprietary driver after upgrading to Ubuntu 21.10, so the older kernel remained without the Nvidia modules.
I'm not sure at the moment if this still a bug for this place. I'll leave this decision to you guys. At least, it will be useful for other people with the same issue.
