Why doesn't RenderingDevice.texture_update work?

Question

Hey!
I just tried using the RenderingDevice.texture_update interface to update the texture data in the RenderingDevice. During testing, I noticed that the texture_update interface call seems to have no effect.
After calling texture_update, I used the texture_get_data interface to retrieve the data from the texture, but the returned value is not the data I passed in for the update. Could you please tell me why this is happening? Is there an issue with how I am using the interface?

Here’s the relevant code :

func _ready() -> void:
	rd = RenderingServer.get_rendering_device()
	
	var new_image = Image.new()
	new_image.load("res://test.png")
	print(var_to_str(new_image.get_format()))
	new_image.convert(Image.FORMAT_RGBA8)
	print(var_to_str(new_image.get_format()))
	
	var tf := RDTextureFormat.new()
	tf.format = RenderingDevice.DATA_FORMAT_R8G8B8A8_UINT#RenderingDevice.DATA_FORMAT_R8G8B8_SRGB
	tf.texture_type = RenderingDevice.TEXTURE_TYPE_2D
	tf.width = new_image.get_width()
	tf.height = new_image.get_height()
	tf.depth = 1
	tf.array_layers = 1
	tf.mipmaps = 1
	tf.usage_bits = (
		RenderingDevice.TEXTURE_USAGE_CAN_UPDATE_BIT |
		RenderingDevice.TEXTURE_USAGE_CPU_READ_BIT |
		RenderingDevice.TEXTURE_USAGE_CAN_COPY_FROM_BIT |
		RenderingDevice.TEXTURE_USAGE_CAN_COPY_TO_BIT
	)
	var texture_rd = rd.texture_create(tf, RDTextureView.new(), [])
	
	var ret = rd.texture_update(texture_rd, 0, new_image.get_data())
	
	var ret_data = rd.texture_get_data(texture_rd, 0)
	if ret_data && !ret_data.is_empty():
		new_image = Image.create_from_data(new_image.get_width(), new_image.get_height(), false, Image.FORMAT_RGBA8, ret_data)
		new_image.save_png("ret_save.png")
	return
