When highlighting a body or feature, the highlighting appears faceted or jagged.
Solution If the highlighting is not smooth, or appears with a facet or facets when the cursor rolls over the selectable object, this can be controlled by the Selection Preference 'Highlight Original'.
In the Menu, select 'Preferences-->Selection'.
If 'Highlight Original = ON', the highlighting can appear faceted.
If 'Highlight Original = OFF, the highlighting should appear more precise.
