[New-bugs-announce] [issue43679] ttk.Sizegrip disappears under Windows 10 UI Scaling, with dpiAware set true and >1 scaling

[MikeS]

New submission from MikeS <mikesmithpanda at protonmail.com>:

When using tkinter on Windows (10) with a >1 HiDpi screen the sizegrip disappear with dpiawareness is on. A minimal example is as follows:

import tkinter as tk
import tkinter.ttk as ttk
from ctypes import windll, pointer, wintypes
windll.shcore.SetProcessDpiAwareness(1)

root = tk.Tk()
btn1 = tk.Button(root, text='btn1').pack(side=tk.LEFT)
sg = ttk.Sizegrip(root).pack(side=tk.LEFT)
btn2 = tk.Button(root, text='btn2').pack(side=tk.LEFT, fill=tk.BOTH, expand=1)
root.mainloop()

Works fine with commented "SetProcessDpiAwareness", but not when using it. This might be related to the tk issues with hidpi and small radio/checkboxes https://bugs.python.org/issue41969
