GeoJSON stroke rendering odd when options parameters used

CesiumJS
1

I’m using this code to render the GeoJSON:

var dataSource = new Cesium.GeoJsonDataSource();
viewer.dataSources.add(dataSource);
dataSource.load(geojson, {
stroke: Cesium.Color.BLACK,
fill: Cesium.Color.DARKKHAKI,
strokeWidth: 5
});

``


When I zoom in, it loses it’s stroke:

When I leave out the options parameters, everything is fine.

I’m not sure if it’s a GeoJSON, Cesium, and/or WebGL problem.

Any thoughts on how I should add the color to the GeoJSON?

Thanks!

This is using 1.6

There are two possibilities: Does it also happen when using non-opaque colors? i.e. Cesium.Color.DARKKHAKI.withAlpha(0.5)

You may be running into this bug: https://github.com/AnalyticalGraphicsInc/cesium/issues/2333

Non-opaque works great!

It definitely sounds like said bug.
