Existing entities blinking/disappearing on adding new entity

I have the following scene I am using within my game. It’s a simple Tiled Map with a single button ‘UI’. I start the scene with some entities and have my update method spawn new entities on click. The spawned entities on initialization are placed on the tiled map properly but when added by mouse click, the existing and new entities just blink after each click. The debug borders around the entities are still visible but the sprites of the entities blink. Is this a bug?

public class GameScene : Scene
{
        public override void initialize()
        {
            // Set scene background color
            clearColor = Color.Black;

            Core.debugRenderEnabled = true;

            // Set camera zoom
            camera.setZoom(1);

            // Add the renderers
            addRenderer(new ScreenSpaceRenderer(100, UI.UI_RENDER_LAYER));
            addRenderer(new RenderLayerExcludeRenderer(0, UI.UI_RENDER_LAYER));

            var map = content.Load<TiledMap>("maps/Fardia");
            addEntity(new UI());
            addEntity(new Map(map));
            addEntity(new God());

            for (int i = 0; i < 100; i++)
            {
                var position = Nez.Random.range(new Vector2(10, 10), new Vector2(100, 100));

                addEntity(new Human()
                {
                    position = position
                });
            }
        }

        public override void update()
        {
            base.update();

            if (Input.leftMouseButtonPressed)
            {
                addEntity(new Human()
                {
                    position = camera.mouseToWorldPoint().round()
                });
            }
        }
    }
