If you look at http://rpgoldman.real-time.com/goofy-clim.png you will see what happens when one of my panes runs a display-function that calls format-graph-from-roots inside updating-output. The display does not all get updated, leaving funny gray borders around the active area of two panes.
I have seen gray borders also under other circumstances, i.e. in some cases when displaying text.
