Description of problem:

Metacity does not unmaximize windows reliably.  What I mean is that
occasionally when a window is maximized metacity seems to forget what the
original size was.  When that happens, when metacity forgets, either pressing
<alt><f5> or clicking the unmaximize button in the upper right hand corner
does cause the window to change to the unmaximized state, but it retains its
large maximized size.

Version-Release number of selected component (if applicable):

I've reproduced this problem on both Fedora 8 and Fodora 9 preview (Fedora
release 8.93 (Rawhide)), so it's probably in the latest metacity code.  But I
have not actually built from latest source code.  The metacity versions are:
    metacity-2.20.0-3.fc8
    metacity-2.22.0-2.fc9.i386

How reproducible:

This problem is intermittently reproducible during normal use.  I think I
experienced it once every five minutes or so which was enough to annoy me into
moving to IceWM.

However, I can recreate this problem in a matter of seconds using the
artificial recreate steps mentioned below.  So in that sense it's very
reproducible.

Steps to Reproduce:
1. Open some application that normally does not startup maximized.  
   gnome-terminal works well.
2. Use the keyboard shortcuts to quickly alternate between the maximized and 
   initial unmaximized sizes.  With the default bindings just hold down the
   <alt> key and alternately press <alt><f10> and <alt><f5> quickly.
3. After a while although <alt><f5> causes the application to enter the 
   unmaximized state it's now roughly the maximized size.  In other words, the
   size of the application no longer varies significantly as <alt><f5> and
   <alt><f10> are pressed.
  
Actual results:

Either pressing <alt><f5> or clicking the unmaximize button in the upper right
hand corner fails to cause the window to return to the size it was when the
application was first displayed.  Instead, it ends up being pretty much the
maximized size.

Expected results:

Either pressing <alt><f5> or clicking the unmaximize button in the upper right
hand corner should cause the application to return to the size it was when the
application was first displayed.

Additional info:

It surprises me that I can't find any other complaints about this.  Maybe it
only happens on older machines, but my "Intel(R) Pentium(R) 4 CPU 3.00GHz"
isn't that old.  It also happens on my much older "Pentium III (Katmai)".
Maybe many people experience this, but only I was annoyed enough to open a
defect as a result of the way I work with windows.  I like to have multiple
gnome-terminals that are precisely 80x24 tiled across my desktop (four, one in
each corner). I'll maximize whichever one I'm using.  And I like it to go back
to exactly 80x24 when I'm done.  If you don't care what it gets unmaximized to
then dragging it back manually isn't so bad.
