tkinter gif问题：黑色变为白色，以前的框架不会消失

Question

我正在尝试在Python编码桌面宠物。为此，我主要使用了TKINTER。我设法创建了一个带有两个GIF的窗口，这些窗口彼此跟随，但是我对框架的显示有问题。正如您在图片中看到的那样，黑色变为白色，有时它完全消失了……此外，对于其中一个GIF，两个帧同时出现，一个以前的＆nbsp;一个停留而不是消失。＆nbsp;＆nbsp;

这是我的代码：

import random
import tkinter as tk
import pyautogui

impath = '.\\Assets\\'

x = 1400
cycle = 0
check = 0

probality=10
idle_num = list(range(0,7))
cry_num = list(range(7,11))
event_number = random.randrange(probality)

#transfer random no. to event
def event(cycle, check, event_number, x):
    if event_number in idle_num:
        check = 0
        print('idle')
        window.after(500, update, cycle, check, event_number, x)

    elif event_number in cry_num:
        check = 1
        window.after(500, update, cycle, check, event_number, x)

# make the gif work
def gif_work(cycle, frames, event_number):
    if cycle < len(frames) -1:
        cycle += 1
    else:
        cycle = 0
        event_number = random.randrange(probality)

    return cycle, event_number

def update(cycle, check, event_number, x):
    # idle
    if check == 0:
        frame = idle[cycle]
        cycle, event_number = gif_work(cycle, idle, event_number)

    # cry
    elif check == 1:
        frame = cry[cycle]
        cycle, event_number = gif_work(cycle, cry, event_number)
    
    window.geometry('842x842+' + str(x // 2) + '+50')
    #window.geometry('100x100+' + str(x // 2) + '+930')
    label.configure(image=frame)


    window.after(1, event, cycle, check, event_number, x)


window = tk.Tk()

# call buddy's action .gif to an array
idle = [tk.PhotoImage(file=impath + 'existerGif.gif', format='gif -index %i' % (i)) for i in range(3)]  # idle gif , 4 frames
cry = [tk.PhotoImage(file=impath + 'placeGif.gif'   , format='gif -index %i' % (i)) for i in range(8)]  # sleep gif, 8 frames


window.config(highlightbackground='white')
label = tk.Label(window)
window.overrideredirect(True)
window.wm_attributes('-transparentcolor','blue')

label.pack()

#loop the program

window.after(1,update,cycle,check,event_number,x)

window.mainloop()

也许这是一个格式问题，我在Photoshop上使用PNG图像进行了gif。

无论如何，如果有人有一个主意，我会很高兴听到它^^ 祝你今天过得愉快！
