Thanks for the response. I'm running Xubuntu with the defaults. I did see that other bug report and noticed that the comment in number 4 (https://bugs.launchpad.net/ubuntu/+source/xscreensaver/+bug/1989163/comments/4) mentions the preview button problem. However, I don't have the problems they are talking about in running from the menu, but I'm not using Lubuntu.
