I just had a patch uploaded a few hours ago that makes sure that the
capture_before_unmap key is disabled by default in the metacity
package. It is waiting for approval.
@Colin: as Bill said having some extra information about if the
corruption is still reproducible after that key is set to false
What's supposed to be responsible for setting capture_before_unmap to
true? Right now, it's simply set to true in metacity.schemas, which
doesn't fit with how Bill is saying it's supposed to work.
I generally notice this problem when switching workspaces, although it
doesn't happen in every such
@colin
couple of things here:
- capture_before_unmap should be set to false by default in metacity.schemas,
so that is a definitely a bug
- unity-2d package should set capture_before_unmap to true in it's
debian/20_unity-2d-gconf-default file which sets the gconf defaults for the

Please make sure the capture_before_unmap gconf setting is false by default. It
should only be true when logging into unity-2d session.
@marc
Can you come up with a reliable way to reproduce the corruption without using
unity-2d?
This is what I was doing to test:
1- On workspace 1, open firefox, and three terminals. Try and stagger windows
2- Do the same on workspace 2
3- for 10 minutes, switch between workspaces, and switch between windows

Ugo (original writer of the patch) will look into the issue as we really need
that patch to be in there and working properly for Unity 2D.
The GConf key /apps/metacity/general/capture_before_unmap is supposed to be set
to false by default and only to true when logging in a Unity 2D session.

Both screenshots are from the -intel box.
The black smudge over the trashcan is the corruption, the overlapped
