That's the problem.
The one where the window manager decided to put the window?
(Ok, there may be a bit of a catch-22 here: You might want that
information before actually creating the window, but the window manager
can only place the window once it's created. Plus the placement might
depend on the size.)

Well, that's obviously a bug. (Presumably the programmer didn't expect
there to be more than one screen, or at least not screens of different
sizes.)

You still haven't answered the question: Where should the initial window
size come from? Does your window manager tell the application how large
a window should be? And if it does, can you as a user configure that? I
don't think mine (xfce) does that. (I guess tiling WMs generally do
that, but I've never used one.)
