Happen to me (xscreensaver/bumps) on Ubuntu9 13.10 amd64 after copying an exremley large file (77.5GB). Xscreensaver was left running so I can't exactly say when it appered

This issue is fixed in 5.22.

README in xscreensaver 5.22:
* Fix for `bumps' in 64 bit.

(As I wrote in the previous comment, this issue is really 64 bit specific, does not happen on 32 bit)

Not fixed for 6 years. Should not be this complex I think

Ubuntu 13.10 <xscreensver was running as were two downloads>

I have a pre-release for xscreensaver 5.22 in my PPA, if anyone wants to install that instead. It is the Debian version without Ubuntu patches, so you might want to remove the old packages before installing these to avoid certain upgrade issues. The Precise package should work fine in any newer release as well.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug was fixed in the package xscreensaver - 5.26-1ubuntu1

---------------
xscreensaver (5.26-1ubuntu1) utopic; urgency=low

  * Dropped Ubuntu changes:
    - Ubuntu delta to the screensavers sets.
    - Keep Debian Vcs-* links instead of the ~ubuntu-desktop team bzr
      repository: the Desktop team does not have interest any more.
    - The Ubuntu changes to the descriptions.
  * Merge from Debian unstable. (LP: #1283459) Remaining changes:
    - debian/control:
      + Breaks/Replaces: the old changes are not needed anymore, but the
        new changes the screensavers sets needs it.
    - debian/rules:
      + Use /usr/share/backgrounds as image directory.
      + Add translation domain to .desktop files.
    - debian/source_xscreensaver.py:

    - debian/xscreensaver.dirs:

    - debian/patch/90_ubuntu-branding.patch: Use Ubuntu branding.
    - debian/patches/60_sequential_glslideshow.patch:
      + Allow going through images sequentially rather than just at random in
        the GLSlideshow hack.
