Certain combinations of screensaver hacks, graphic drivers and cards cause unexpectedly high CPU loads. In my PPA at https://launchpad.net/~tormodvolden/+archive/ubuntu/ppa there is xscreensaver 5.45 for focal, with an extra patch that displays a CPU load summary for each hack in the verbose log. I hope this can help to collect more data.
