Python GIF显示但很难看

Question

这是代码，真的显示了gif，但是很丑......我试图使用PIL，但是同样的bug。按照2个代码（我自己的第一个，网络的第2个）和打印：

gif文件（是一个随机文件要测试，这么可爱吧？kk）：

请看截图了解：

第一个代码：

import tkinter as tk
from tkinter import Canvas, PhotoImage

x = 0

def animate(self):
    global x
    if x == 32:
        x = 0
    else:
        self.pic["format"] = "gif -index " + str(x)
        self.label1["image"] = self.pic
        x += 1

    print(x)

    self.after(50, lambda: animate(self))


class run(tk.Tk):

    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)

        self.pic = PhotoImage(file="/home/arnaldo/Desktop/b.gif", format = "gif -index 0")

        self.label1 = tk.Label(width=350, height=233)
        self.label1.pack(expand="yes", fill="both")

        animate(self)

run().mainloop()

我在网上找到的第二个代码：

from tkinter import * 
from PIL import Image, ImageTk


class MyLabel(Label):
    def __init__(self, master, filename):
        im = Image.open(filename)
        seq =  []
        try:
            while 1:
                seq.append(im.copy())
                im.seek(len(seq)) # skip to next frame
        except EOFError:
            pass # we're done

        try:
            self.delay = im.info['duration']
        except KeyError:
            self.delay = 100

        first = seq[0].convert('RGBA')
        self.frames = [ImageTk.PhotoImage(first)]

        Label.__init__(self, master, image=self.frames[0])

        temp = seq[0]
        for image in seq[1:]:
            temp.paste(image)
            frame = temp.convert('RGBA')
            self.frames.append(ImageTk.PhotoImage(frame))

        self.idx = 0

        self.cancel = self.after(self.delay, self.play)

    def play(self):
        self.config(image=self.frames[self.idx])
        self.idx += 1
        if self.idx == len(self.frames):
            self.idx = 0
        self.cancel = self.after(self.delay, self.play)        


root = Tk()
anim = MyLabel(root, '/home/arnaldo/Desktop/a.gif')
anim.pack()

def stop_it():
    anim.after_cancel(anim.cancel)

Button(root, text='stop', command=stop_it).pack()

root.mainloop()

两个都是丑陋的GIF ......
