Package: xscreensaver
Version: 4.21-3
Followup-For: Bug #302777
I get this reliably too. I also use the nvidia proprietary driver.
I set up a trivial shell loop to monitor CPU usage when the preview (I
happened to use twang) started, as well as when it ended, and it looks
to me like the process actually goes berserk at the start of the
preview, not at the end. I don't know whether that helps at all:
% while sleep 1; do date; ps -eo
etime,time,pid,user,args --sort %cpu|grep 'xscreensaver-|twang'|grep -v
reportbug; done
[[ Shortly before I start xscreensaver-demo; it starts the mini-twang,
neither are eating any significant CPU ]]

starts eating just under 1 cpusecond per second around now. I presume it
would be eating it all, if twang weren't trying for some. ]]
