[OpenLayers-Users] LineString in Vectorlayer doesn't get rendered in Firefox

[Andreas Hocevar]

This is probably because your feature spans a very large area of the
world. Firefox has a limited range of coordinate values, so there is
some extra logic in the SVG renderer to split geometries, which does
not catch all cases. As a workaround, you may want to try the Canvas
renderer instead.
