FeatureNodes flickering because of depthOffsetOptions
some of my FeatureNodes where collapsing under the surface of the map. For example when there was a line drawn near 0, 0 WGS coordinates only it's beginning and end was visible, so i applied DepthOffsetOptions for it to render properly:
Re: FeatureNodes flickering because of depthOffsetOptions
Depth offsetting can only do so much and will typically only work over a very small area. You also will need to tessellate your geometry. Try using the LineSymbol::tessellationSize property to limit the length of any individual line segment.
