Resolution Note:
The vertex count of the Sprite exceeds the maximum Vertex Count that satisfies the requirement for Dynamic Batching.
Batching dynamic GameObjects has certain overhead per vertex, so batching is applied only to Meshes containing no more than 900 vertex attributes, and no more than 300 vertices.
