This happens for me when I start gedit via Applications -> Accessories -> Text Editor with xserver-xgl 7.2.0.git.20070224-0ubuntu3 and the same version of compiz and desktop effects. Confirming.
** Changed in: compiz (Ubuntu) Status: Unconfirmed => Confirmed -- Compiz makes gedit open on all workspaces initially https://launchpad.net/bugs/93622 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
