Because the window manager gets the opportunity to place the windows
when they're created.

First, the window may be positionned from what defaults are given in
~/.Xresources ; check a line such as: emacs.geometry: 81x71-68+0

Then the window manager may position the window (notably, most window
manager add decorations above the window (eg a title bar) so it will
actually move the windows down by the title bar height).  Often it's
not visible, because it's done before drawing the window, but you can
see it if you open the window before starting the window manager.

Finally, ~/.emacs may contain expressions to move and size the frames.
Yes, from emacs lisp it's not "window" anymore but "frame" we're back
on the right side of the mirror here :-)


So you can avoid jumping by giving consistent positions and sizes in
all these places, or by removing the later sizing and positionning.
