I can confirm that this affects xscreensaver 5.15-2ubuntu1 in Xubuntu 12.04.5 with xfdesktop 4.8.3-2ubuntu7.
Personally I think it is a big shame that such things are disregarded, as it can be understand form the link posted by Vernon Mauery: [Quote] The screensaver activates when I'm not idle! It's not noticing my mouse clicks or mouse wheel. On most X11 systems, this is unfortunately the case, and there's no way around it. XScreenSaver notices all keyboard activity; and every few seconds, it checks the position of the mouse. If there have been no keystrokes or mouse motion, it assumes you are idle. It cannot detect mouse clicks, nor the scroll wheel. This is because, for no good reason, the X Window System does not allow programs to "snoop" on mouse clicks (though snooping of keystrokes and mouse positions is permitted!)
