am using GeoJsonDataSource with Viewer widget to render vector lines and facing two issues:
When dragging map, terrain and base layer are dragged faster then vector features (this is issue is also present at cesium sandcastlehttp://cesium.agi.com/Cesium/Apps/Sandcastle/?src=Polylines.html)
when zooming in, at bigger zoom levels, lines disappear (can partially disappear) then appear again. (seems like lines do not honour terrain model)
Are these bugs? I didn’t find such issues described on github or here.
