Bug#452139: metacity: vertical maximization problem on dual-screen setup

[Eric Cooper]

Package: metacity
Version: 1:2.20.0-1
Severity: normal

I have a dual-screen setup (using the X radeon driver's "MergedFB"
option, not Xinerama).  I use "devilspie" to vertically-maximize my
gnome-terminal windows.

When I move one of these windows to the other screen, it gets resized
vertically by 26 additional pixels, enough to put the last line below
the Gnome panel on the bottom edge.

I think this used to work fine until this version of metacity.
(I only logged out of my desktop recently, and the upgrade happened a
couple of weeks ago, so I can't be sure.)

Here's the geometry when I first create a terminal window:
  Width: 882
  Height: 1113
And this is after moving it to the other screen:
  Width: 882
  Height: 1139

I have Gnome panels on the bottoms of both screens, with height 25.  The
26-pixel difference in heights made me think there is some interaction
there, so I tried a few experiments.

When I move the panel on the second screen to the side, rather than
the bottom, the terminal window there is resized
all the way to the bottom of the screen.

And if I then move the panel back to the bottom, the window is
correctly shortened to fit above the panel, and the problem seems to
be fixed.  New windows that I create can be moved back and forth
between the two screens without the extra lengthening.

I'm working around this for now by using an explicit geometry in my
devilspie rule, rather than maximize_vertically.
