opencv python not resizing window

I'm trying to get Opencv to work and by running the PixelBotTest.py script below I get a window that is just 64 by 64 literal pixels and not 64 by 64 scaled with 8 as it should do in the PixelBot class.
When I comment out cv2.resizeWindow it does the same thing so it looks like it's just ignoring it?
I tried to use WINDOW_OPENGL but that just makes it extremely blurry.

    ***PixelBot.py***
import cv2
import numpy as np

class PixelBot:
    def __init__(self, x: int = 64, y: int = 64, windowScale: float = 8) -> None:
        self.map = np.zeros([x,y,1], dtype=np.uint8)
        self.pos = [0, 0]
        self.map.fill(255)
        cv2.namedWindow("PixelBot", cv2.WINDOW_NORMAL)
        cv2.resizeWindow("PixelBot", x * windowScale, y * windowScale)

    def startPixelBot(self, x:int = 0, y: int = 0):
        self.pos = [x, y]
        self.setPos(self.pos[0], self.pos[1])

    def setPos(self, x:int, y:int):
        self.map[self.pos[0], self.pos[1]] = 255
        self.pos = [x, y]
        self.map[self.pos[0], self.pos[1]] = 0
        cv2.imshow("PixelBot", self.map)

    ***PixelBotTest.py***
from PixelBot import PixelBot
import cv2

bot = PixelBot()
bot.startPixelBot()

for i in range(500):
    bot.setPos(i,i)
    cv2.waitKey(1000)
