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.
Please ignore the above comment. It seems what I'm experiencing is a
different bug.
If I run the following, I get high CPU
glslideshow -delay 0 -zoom 100 -pan 1
If I run the following, I get low CPU
glslideshow -zoom 100

I think I'm getting the same bug.
20.04 Linux: 5.8.0-55-generic xscreensaver: 5.42+dfsg1-1ubuntu1
I'm configured to run glslideshow
If I run `xscreensaver & xscreensaver-command -activate` I get high CPU

If I run `/usr/lib/xscreensaver/glslideshow` directly,
Still happens on 20.04 all up to date on kernel 5.4.0-70-generic (on the
