1. It works when the DALI_PARTIAL_UPDATE_AVAILABLE environment variable is set.
2. Add Update Size Hint property
- By default, it works with the size of the render item.
If you set the UPDATE_SIZE_HINT property, the update size hint determines the update area.
ex)
Vector2 updateSizeHint = Vector(width, height);
mView1.SetProperty(Dali::DevelActor::Property::UPDATE_SIZE_HINT, updateSizeHint);
