Go with Fast Rendering on.  The line appears to be a side effect
of the handling of projection seams. 

In general, if you are displaying data
in its native format, you should set your preference to use
Fast Rendering.  This ignores projection seams and saves on
time and memory consumption.  See the section in the User's
Guide on Performance Tuning for more tips.
