just to bump this up, the issue is still active in the scenery editor, the
yellow polygons are squared as follows
the polygons became distorted (polygons are drawn on top of a painted line to
make the effect more standing out)
(similar issue for another user
in the forums <https://forums.flightsimulator.com/t/default-scene-library-
with-msfs/594624/5?u=mamudesign>) coords in the source .xml are 100% correct
and square could the that the
polygons coords are somewhat rounded?
