[Tkinter] Text input OK on Windows, not working on linux

[Ota]

window.overrideredirect(True)

is OK on Windows,

window.wm_attributes('-type', 'splash')

is OK on Linux.

I was unable to find a way to hide the title bar which would work on both without creating some issues. Fortunately, it is easy for Python to figure out on which OS it is running and adapt to it accordingly.
But if there is someone who knows if there is a way common for both OS's, I'd like to know howit
