Maybe one of the graphics packages you are running is mucking with the color
map.  One of my coworkers was complaining to me that an ipasted image of
herself had white spots in the hair.  I popped up up showmap to watch the
color map and then did a makemap to restore the default color map.  Viola', the
white specks disappeared.  The changes in showmap showed my which color map
entries changed.

Next time the white dots appear, try running makemap.  Either it will
convince you that the problem is due to colormap contention or it will
convince you that the problem lies elsewhere.
