Unity c#列表内存泄漏

在运行时分配纹理时，我得到了严重的内存泄漏。

当useNewArray为true时，任务管理器显示Unity的内存使用增长了~ 20mb/秒。

下面是我的代码:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class testMemory : MonoBehaviour {
public bool             useNewList = false;
Texture2D               newTexture;
public byte             color;
List<Color>             newColors;
List<byte>              staticPixelColorsList;
Color                   tempColor = Color.white;
// Use this for initialization
void Start () {
    newTexture = new Texture2D(0,0);
    newColors = new List<Color>();
    staticPixelColorsList = new List<byte>(120000);
    GetComponent<Renderer>().material.mainTexture = newTexture;
}
// Update is called once per frame
void Update () {
    // Make sure we're using different colors for every frame
    color = (byte)((Time.time*255) % 255);
    if(useNewList)
    {
        // This option causes a memory leak, but it's the one I need 
        // because I'm getting the texture data from an external source
        int newWidth  = Random.Range(200,400);
        int newHeight = Random.Range(200,400);
        // Create a new list each time
        List<byte> newPixels = new List<byte>(newWidth * newHeight);
        for(int i = 0; i < newWidth * newHeight; i++)
        {
            newPixels.Add ((byte)(color * i / 120000f));
        }
        setTexture(newPixels, newWidth, newHeight);
        // Clear the list (yeah, right)
        newPixels.Clear ();
    }
    else
    {
        // Use the same list, but assign new colors
        for(int i = 0; i < 120000; i++)
        {
            staticPixelColorsList.Add ((byte)(color * i / 120000f));
        }
        setTexture(staticPixelColorsList, 300, 400);
        staticPixelColorsList.Clear ();
    }
}
void setTexture(List<byte> inputPixels, int inputWidth, int inputHeight)
{
    newTexture.Resize(inputWidth, inputHeight);
    float colorValue;
    // Convert input value to Unity's "Color"
    for(int n = 0; n < newTexture.width * newTexture.height ; n++)
    {
        colorValue = inputPixels[n] / 255.0f;
        tempColor.r = tempColor.g = tempColor.b = colorValue;
        newColors.Add (tempColor);
    }
    // Actually set the texture pixels
    newTexture.SetPixels(newColors.ToArray());
    newTexture.Apply();
    newColors.Clear();
}
}
