last_mouse_x and last_mouse_y will change only if you use GPM mouse on
the terminal.  Otherwise, these variables will remain zero on
GNU/Linux.  So what you see is expected unless you use GPM (do you?).

The doc string of x-popup-dialog says that if POSITION is t, then the
dialog appears at the center of the selected frame.  So what you see
is exactly what the documentation says, and I don't understand what is
the problem you are trying to solve, or why POSITION being t is
important to you, or where you expected or wanted the dialog to pop up
or why there.  Please elaborate, as I feel we are talking past each
other.

I see the same on a GUI frame, btw, so I also don't understand what
"works as expected in gui" for you.

What am I missing?
