This is actually a problem not with xournal, but with libgnomecanvas -- I'm assuming there was a faulty update to libgnomecanvas in Ubuntu. This bug has first affected various versions of OpenSUSE, where it was first evidenced, then fixed, then reappeared...
The immediate solution is to get the libgnomecanvas packagers for Ubuntu to *not* include a patch called libgnomecanvas-no-tearing.diff, or to include an updated patch that can be found attached to the latter of the two bug-reports mentioned above.
