Mapbox-gl-native: Adding marker to offline map only appears after movement

[dsuresh-ap]

Platform: Android
Mapbox SDK version:5.0.2 and 5.5.1

Steps to trigger behavior

1. Download map region
2. Kill app and disconnect wifi
3. Restart app
4. Add marker
5. Remove marker and add another marker

Expected behavior

Old marker gets removed and new marker gets displayed

Actual behavior

Old marker gets removed, new marker only gets displayed on the slightest map movement. Annotation manager shows correct number of annotations. (2, 1 for user location, 1 for marker)

Connecting back to internet shows marker.

Thanks for reporting the issue @dsuresh-ap.

I was able to reproduce:

When the map is in the state that doesn't show markers after a click it's because there always exists a not fully rendered source here, which prevents markers invalidation here.

On both release-boba and release-agua a couple of DID_FINISH_RENDERING_FRAME events are delivered, but not followed up with a DID_FINISH_RENDERING_FRAME_FULLY_RENDERED.

An alternative would be using a SymbolLayer or Markers instead of MarkerViews.

@LukasPaczos We intended to switch to SymbolLayers but right now is there any workaround to the issue?

We are adding the Marker using the following code:
marker = mapboxMap.addMarker(new MapBoxMarkerViewOptions() .position(latLng) .anchor(0.5f, 0.5f) .markerIcon(createMapBoxIcon()) .title(mapObject.getLabelName()));

@dsuresh-ap At this point, if you are not performing any View specific operations on those markers, the only workaround I can see is using MarkerOptions instead of MarkerViewOptions and LocationLayerPlugin for displaying user's location instead of MyLocationView.

@dsuresh-ap Noting, that a temporary workaround might also be using

mapboxMap.getMarkerViewManager().invalidateViewMarkersInVisibleRegion();

after adding a marker.

Workaround for deprecated API given, follow up ticket tackling core side of things in https://github.com/mapbox/mapbox-gl-native/issues/11688.

@LukasPaczos @tobrun The workaround works provided we postDelayed. Also we noticed the same during rotation.
