A test case is good to have too :-).
COORD_CONV factors are applied in common code, before switching between
hardware and software rendering, so I'm a little curious about how this
could happen.

Can you elaborate a little? Describe your problem visually. Also,
information on your version of IDL, OS and graphics interface is helpful.
That said, the general rule of thumb is to make sure you have the latest
graphics driver available for your video card.
