Python 使用透明的 TKinter 表单时，是否可以以某种方式平滑字体并消除伪影

我try 使用TKinter来创建一个简单的应用程序，这通常是我喜欢的工作方式.然而，在使用透明形式时，存在一些美学问题.我在黑底悬停时使用的字体是白色像素边框.

有没有可能以某种方式摆脱这种"神器"？随着ClearType的使用，"构件"变少了，但它们仍然存在，这使得应用程序看起来很难看.

以下是我相当简单的代码:

from tkinter import *
import tkinter.font
import sys
import pyglet
from datetime import datetime, timedelta
import re

bgc = "#ffffff"
fgc = "#e34646"
pyglet.font.add_file("digital_7mono.ttf")

def timer(start_time):
    now_time = datetime.now()
    delta = now_time-start_time
    delta = '{:02d}'.format(delta.days//3600) + ":" \
            + '{:02d}'.format(delta.seconds//60) + ":" \
            + '{:02d}'.format(delta.seconds)
    #delta = delta.strftime("%H:%M:%S")
    return [delta, now_time]

class timerWindows(Tk):
    def __init__(self, *args, **kwargs):
        Tk.__init__(self, *args, **kwargs)
        self.overrideredirect(True)
        self.title("Timer")
        self.geometry('420x110')

        self.wm_attributes("-topmost", True)
        #self.wm_attributes("-disabled", True)
        self.wm_attributes("-transparentcolor", "white")

        self.resizable(width=False, height=False)
        self.configure(bg = bgc)
        font = tkinter.font.Font(family="digital-7 Mono", size=80)
        #self.start_time.strftime("%H:%M:%S")
        self.l1 = Label(text = "00:00:00", bg = bgc,  font=font, )#fg = fgc)
        self.l1.configure()
        self.l1.grid(row=0, column=0, )#padx=5, sticky=NW)
        self.grid_rowconfigure(0, weight=1)
        self.grid_columnconfigure(0, weight=1)
        self.bind("<Button-1>", self.form_click)
        self.bind('<Double-Button-1>', self.double_form_click)
        self.bind('<B1-Motion>', self.on_drag)

        self.menu = tkinter.Menu(self, tearoff=0)
        self.menu.add_command(label="Закрыть", command=self.close_time)
        self.bind("<Button-3>", self.show_popup)
        #self.text.grid()

        self.start_time = datetime.now()
        self.pause_time = self.start_time
        self.checkpoint = True
        self.time_delta = timedelta(0)

    def on_drag(self, event):
        rect = re.fullmatch(r'\d+x\d+\+(?P<x>-?\d+)\+(?P<y>-?\d+)',
                            self.geometry()).groupdict()
        # NOTE: self.winfo_root*() is content's coordinate without window decorations
        x = int(rect['x']) + (event.x - self.start_x)
        y = int(rect['y']) + (event.y - self.start_y)
        self.geometry(f'+{x}+{y}')

        if self.checkpoint==True:
            self.checkpoint=False
        else:
            self.checkpoint = True
            self.start_reading(self.checkpoint)


    def double_form_click(self, event):
        self.checkpoint=False
        self.start_time = datetime.now()
        self.pause_time = self.start_time
        self.time_delta = timedelta(0)
        self.l1['text']="00:00:00"

    def start_reading(self, arg):
        if arg:
            if self.pause_time>self.start_time:
                self.start_time=datetime.now()
            start_time_return = timer(self.start_time-self.time_delta)
            self.l1['text'] = start_time_return[0]
            self.l1.update()
            self.after(1000, self.start_reading, self.checkpoint)  # repeat the call
        if not arg:
            self.pause_time=datetime.now()
            self.time_delta = self.time_delta+(self.pause_time-self.start_time)

    window = timerWindows()
    window.after(1000, window.start_reading, True)
    window.mainloop()
