Public bug reported:
Binary package hint: metacity
New application windows pick up some partial notion of "maximized" by
virtue of having been created with a maximal width or height.
"maximized" is conceptually distinct from "at maximal width/height"--
windows created with the latter attribute shouldn't assume the former.
Steps to recreate in the vertical using Firefox are described below.
The problem is not restricted to Firefox (I can recreate with gedit),
nor to the vertical (I can recreate in the horizontal as well).
To recreate:
- Open a new Firefox instance. Arrange that the new instance will open
in a window that's smaller than maximum in both horizontal and vertical
directions and is not adjacent to either panel or left or right screen
edges.
- Move the initial Firefox window so the top of the window is adjacent
to the top panel.
- Resize the Firefox window vertically so that the bottom of the window
is adjacent to the bottom panel.
- Open a new Firefox window (ctrl-N).
- Note that the original window can be moved and resized both
horizontally and vertically.
- Note that the new window can only be moved and resized horizontally,
not vertically. Note that when the cursor approaches the top or bottom
border of the new window, it changes to the resize cursor, but an
attempt to resize does not work.
- Maximize the new window. Note that when maximized the cursor does not
change to the resize cursor when it approaches a window border.
- Unmaximize the new window. Note that it can now be moved and resized
both horizontally and vertically.
If the initial window is resized to maximal width _and_ height before
the new window is created, then the new window is created fully
maximized and cannot be moved or resized in either direction. The
window can then be unmaximized; it will still be at maximal width and
height, but can then be resized or moved in either direction.

I believe this is a metacity problem, and it looks to me like the
culprit may be in meta_window_place(). The call-chain might be:
meta_window_new_with_attrs() -> meta_window_move_resize_internal() ->
meta_window_constrain() -> place_window_if_needed() ->
meta_window_place()
I suspect the following code:
/* Maximize windows if they are too big for their work area (bit of
* a hack here). Assume undecorated windows probably don't intend to
* be maximized.
*/
if (window->has_maximize_func && window->decorated &&
!window->fullscreen)
{
MetaRectangle workarea;
MetaRectangle outer;
meta_window_get_work_area_for_xinerama (window,
xineramas_list[placed_on],
&workarea);
meta_window_get_outer_rect (window, &outer);
if (outer.width >= workarea.width)
window->maximize_horizontally_after_placement = TRUE;
if (outer.height >= workarea.height)
window->maximize_vertically_after_placement = TRUE;
}
