Mapbox-gl-native: MGLFillStyleLayer are drawn at wrong map-layer

Created on 28 May 2019 · 6Comments · Source: mapbox/mapbox-gl-native

Hey i discovered an issue in version 5.0.0 in the mapbox gl native SDK for iOS.

iOS: 12.2
iPhone XR
Xcode: 10.2

In our app we draw several polygons with the following code:

       `let url = URL(string: overlay.geojson_url)

        // Create source and add it to the map style.
        let source = MGLShapeSource(identifier: "\(overlay.id)", url: url!, options: nil)

        let layer = MGLFillStyleLayer(identifier: "\(overlay.id)", source: source)

        layer.fillColor = NSExpression(forConstantValue: UIColor(rgba: overlay.fill_color))
        layer.fillOpacity = NSExpression(forConstantValue: overlay.fill_opacity as NSNumber)

        let sourceAvailable = sources.filter({$0.identifier == overlay.id})

        if sourceAvailable.count == 0 {

            mapView.style!.addSource(source)

        }

        let annotationLayer = mapView.style?.layers.filter({$0.identifier == "com.mapbox.annotations.points"}).first

        mapView.style!.insertLayer(layer, below: annotationLayer!)`

We expected to see the following behaviour like in version 4.6.0:

Instead the following happened in version 5.0.0:

2019-05-28_09-25-43

The same happens in the Android SDK Version 8.0.0. In addition we discovered that the position indicator in the Android SDK (v.8.0.0) is drawn below buildings in the map.

It looks like fill extrusion layers are being rendered above fill layers. This can be repro'd in iosapp by selecting Add Building Extrusions, then Dynamically Style Polygon.

Hi @jmkiley @kkaefer The same happens to me in the Android SDK Version 8.0.0. Is there any update on this issue?

Thank you very much in advance!
