Freezing on zoom in/out after updating to 3.0.0

Hi, I’m running into issues with the map control freezing/taking a long time to load tiles after 3.0.0. I’m getting a bunch of complaints about that. 3.0.0-rc4 was ok, but I’m noticing this too, here’s a YT video:

I’m scrolling out with the mouse wheel, you can see it kinda freezes and then continues. I’m not seeing any spikes in CPU usage; I haven’t changed my map code. I am using WPF. My init code is pretty simple, it’s just this, simplified:

public class MapConfig {
    public static PlayerMapLayers playerMapLayers;
    public static RemoteMapLayers remoteMapLayers;

    /// <summary>
    ///
    /// </summary>
    /// <returns></returns>
    public static Mapsui.Map ConfigureMap()
    {
        var map = new Mapsui.Map { CRS = "EPSG:3857" };
        map.Home = MapHome;

        Mapsui.Logging.Logger.LogDelegate += (level, message, ex) => {
            if (ex != null)
                System.Diagnostics.Debug.WriteLine($"APP message: {message} | Exception: {ex?.Message}");
        };

        ConfigureTileLayers(map);

        return map;
    }

    /// <summary>
    /// Logic for map centering and moving into the right place
    /// </summary>
    /// <param name="navigator"></param>
    public static void MapHome(INavigator navigator)
    {
        if (playerMapLayers == null || remoteMapLayers == null) {
            return;
        }

        if (playerMapLayers.FlightPlanBoundingBox != null) {
            navigator.NavigateTo(playerMapLayers.FlightPlanBoundingBox);
        } else {
            // See if there are remote flights to zoom in on
            if (remoteMapLayers.RemoteFlightsBoundingBox != null) {
                navigator.NavigateTo(remoteMapLayers.RemoteFlightsBoundingBox);
            }
        }

        // Might be resuming, so center on the player
        playerMapLayers.CenterOnPlayer();
    }

    /// <summary>
    /// The different map layers
    /// </summary>
    /// <param name="map"></param>
    protected static void ConfigureTileLayers(Mapsui.Map map)
    {
        map.Layers.Add(OpenStreetMap.CreateTileLayer());
    }
}

Removing the MapHome doesn’t make a difference. I can downgrade to the rc and it’s fine.
