jQuery Accordion - text jerks when opening new content section


I am using jQuery Accordion here:
http://projectpath.ideapeoplesite.com/rutland/printing-whiteplastisolinks.html
and find some strange behavior when opening a section. The text jerks
and looks dreadful for a second or so and then appears normally. This
only happens when moving down and opening the next section. When I go
the other way, the transition is smooth. Is there a setting that would
remove this behavior?
Thanks.
