tkinter gui glitching out

有人知道为什么我的tkinter在大约2.5分钟后会像这样出现故障吗？

此代码是最小的示例，因此它没有彩色单元格，但这是相同的问题

from tkinter import *
import random

tk = Tk()
tk.wm_title("Battleship")
# forming tkinter window

def baseGrid():
    tk.player_canvas = Canvas(tk,height=300,width=300,highlightbackground='black',highlightthickness=0.5)
    tk.ai_canvas = Canvas(tk,highlightthickness=0.5)
    tk.player_canvas.grid(row=1,column=0,padx=50)
    tk.ai_canvas.grid(row=1,column=1,padx=50)
    for x in range(10):
        for y in range(10):
            tk.player_canvas.create_rectangle(x * 30,y * 30,300,fill='white')
            tk.ai_canvas.create_rectangle(x * 30,fill='white')


while True:
    tk.update()
    tk.update_idletasks()
    place = baseGrid()
