with any PySimpleGUI, tkinter, tk, *.py

The initial window is huge & with a size no widgets are visible

What sets initial window configuration ?

I have removed the Windows component as the issue reported seems to be on Ubuntu (but I don't like removing others from the nosy, so have left that alone).

Tkinter does no initial window configuration created through either `Tk()` or `Toplevel()` as this is all handled by Tk (though I don't believe that would do the behaviour you describe). I cannot reproduce the issue (either with or without the 'size' argument) but suggest you take it up with the PySimpleGui team as they may be doing some custom configuration.

How about the following - title ok but no label visible ?

# t8.py
import tkinter as tk

class Application(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.geometry('500x500')
        self.title('Your first App')

        first_label = tk.Label(self, text = "I'm a cool App!!", font=10, bg="black",fg="red" )
        first_label.pack(pady= 2, padx = 2)

app = Application()
app.mainloop()

That example also works on my setup (see attached). The only reason I could think that your label is not showing is that the font given is not of a valid format (see https://www.tcl.tk/man/tcl8.6/TkCmd/font.htm#M13), though I would have thought this would raise a TclError.

Please confirm what platform and Python version you are using as well as the output of `tkinter.test.support.get_tk_patchlevel()`.

Apologies, you did give the platform and Python version. I presume you are compiling the master branch, in which case do you have the 'tk8.6-dev' package installed?

PySimpleGUI is not a part of the stdlib.

If you have problems with pure Tkinter, look if you have files .Xdefaults or .Xresources in your home directory. They can alter default look of Tk widgets. Try to remove them and test whether the problem is gone.

If the problem is still here, perhaps you have some fonts misconfiguration.

Roundup requires submission inplain text...forget how to turn this off in thunderbird...sounds like a left over from microsoft emailers...how do I see/respond to comments with an issue ?

Good suggestion but same results...
  Tkinter ? Python 3.10 wants tkinter
