PyQt5 resizes tkinter window automatically

I am trying to open a web page using PyQt5 after a button press in tkinter window.

As soon as the new window opens, it resizes (downsizes in this case) the tkinter window permanently.

Minimal code required to reproduce this

import sys
from PyQt5.QtCore import *
from PyQt5.QtWebEngineWidgets import *
from PyQt5.QtWidgets import QApplication
from tkinter import *
from threading import Thread

class Web:
    def __init__(self,url,title='',size=False):
        self.title=title
        self.url=url
        self.size=size

        self.app=QApplication(sys.argv)
        self.web=QWebEngineView()
        self.web.setWindowTitle(self.title)
        self.web.load(QUrl(self.url))
        if size:
            self.web.resize(self.size[0],self.size[1])
    
    def open(self):
        self.web.show()
        sys.exit(self.app.exec_())

def launch():
    web=Web('https://www.example.com')
    web.open()

root=Tk()

button=Button(root,text='open',command=lambda:Thread(target=launch).start())
button.pack(padx=100,pady=100)

root.mainloop()

Images for reference

Both the images have the same height.

I would like to know the reason and a way to prevent this.

I have figured it out myself. PyQt changes the dpi awareness which does not happen by default with tkinter. Due to which the tkinter window resized itself as soon as PyQt was launched in the same main loop.

Since I am on a windows machine, using this solved the problem.

ctypes.windll.shcore.SetProcessDpiAwareness(1)
