python tkinter on CentOS 8.1

Was trying to get an existing python/tkinter gui (from CentOS 7.4) running on CentOS 8.1 and the fonts were all really tiny, spent several hours trying to set default font sizes e.g. TkDefaultFont as follows:

  root = tk.Tk()

  default_font = font.nametofont("TkDefaultFont")
  default_font.configure(size=11)
  root.option_add("*Font", default_font)
  root.option_add('*Dialog.msg.font', default_font)

which was partially successful and got the window fonts back to normal - however 'system' dialogs e.g. messagebox or filedialog were still screwed up

See the answer below....

Turned out that the tk scaling factor was coming back as 'Inf' !?

The solution was to make a TK call to set the scaling factor to '1' - i.e. 1 pixel per point, and everything was back to normal. as follows:

  root = tk.Tk()

  root.tk.call('tk', 'scaling', '1')
  ...

Could not find any internet references to this issue

PS Using Virtualbox and 'server' or 'workstation' install of CentOS 8.1.1911
