OK, I've recreated this. It appears to be related to the ubuntu overlay scrollbars - the ones that just pop up some of the time when you hover over them. If in a terminal you do:
export LIBOVERLAY_SCROLLBAR=0
xlog
you should find it works OK.
(Tried in ubuntu-2d in a vm, I get the problem and it goes away if I do that; doesn't happen on my KDE install where I don't have the overlay stuff).
