[mapguide-internals] RE: Rendering engine issue

[Traian Stanev]

Looks like you zoomed in beyond double precision limits. However, it seemed to me like it was useless to zoom in so far, since all you were doing was zooming in on a single point.

If you want to zoom in further without artifacts, I recommend changing the coordinate system of your data such that the origin (0,0) is somewhere near the area of interest.
