Annotation blinking issue with Mapbox version >8.6.3

[AndrKzntsv]

We've encountered an issue with symbols blinking when changing positions frequently. The setup is exactly like one described in #1043.

SymbolManager instance is configured with iconAllowOverlap set to true:

private val symbolManager =
    SymbolManager(mapboxView, mapboxMap, mapboxStyle).apply {
        iconAllowOverlap = true
    }

The symbol is updated like this:

roverSymbol.latLng = position
symbolManager.update(roverSymbol)

Everything worked fine with the Mapbox version 8.6.3. We check all newer versions – the symbol blinks.

Thanks for the ticket @AndrKzntsv . This flickering is likely the same as discussed at:

• https://github.com/mapbox/mapbox-gl-native-android/issues/392
• https://github.com/mapbox/mapbox-gl-native/issues/16473
• https://github.com/mapbox/mapbox-gl-native-android/issues/360

The fix has already landed in the Maps SDK for Android and will be delivered in the next stable release of the Maps SDK for Android.

Thank you for the quick reply! Will be waiting for the update.

Great, thanks for your patience.

By the way, @AndrKzntsv , along with iconAllowOverlap(), iconIgnorePlacement() is another often-used PropertyFactory method used to control the visual collision of symbols.

See https://docs.mapbox.com/android/maps/examples/symbol-collision-detection and https://docs.mapbox.com/android/maps/examples/marker-symbol-layer

Thanks for the advice. Somehow, I've never experimented with this option.

hi @langsmith is there already a release date for next stable release of the Maps SDK for Android? :)

Hi @langsmith i updated the Android SDK (9.3.0) but unfortunately i'm experiencing the same issue like described in #16473 and obove.

Any thoughts about this behavior?

Validated with v9.4.0 that this is not an issue anymore:

For this I updated Change Symbol example to not update the icon image here. Note that it uses the aforementioned APIs as

          symbolManager.setIconAllowOverlap(true);
          symbolManager.setTextAllowOverlap(true);

Configured here.
