Comment 19 for bug 20384

This bug sounds exactly like what I'm seeing on 2.11.3-0ubuntu2 too. It's really
irritating - it seems to happen every time I shut the lid and come back (ie,
when xscreensaver/unlock stuff is running) and also randomly when I'm working.
Every time metacity restarts, every window slides down the screen by the
distance of the title bar and across to the right a little, and I have to shift
them all back into place. </whine>

I'd love to see the fix uploaded :)
