OK, linux-modules was installed but linux-modules-extra was not. I installed that package and booted from 5.11.0-34 and the distortion is back. I removed it, rebooted, and still the distortion was there, but the desktop and network was working. I cannot repeat what happened the first time I booted 5.11.0-34, but it definitely was that version as journalctl --boot=-6 shows it.
