Same problem here: I'm using 6 viewports (2 rows, 3 columns) in Ubuntu 12.04 running Gnome Classic with Compiz. It appears that the bug is at least to some extent related to workspace switcher applet in panel.
Even more: 1.) A _maximized_ window on a center viewport (that is, upper-center or lower-center) will jump to the corresponding left viewport as soon as: -switching from center viewport to right viewport, either by key or by mouse edge flipping 2.) Even worse: ANY _maximized_ window on a center viewport (that is, upper-center and lower-center) will jump to the corresponding left viewport as soon as: -another application window is launched on either of the right viewports (upper right or lower right). Bug 1.) does not occur if workspace switcher applet is permanently removed from panel. Bug 2.) still occurs, having tested any seemingly relevant ccsm settings. Serrano, could you please test the 'workaround' for Bug 1, and try to reproduce Bug 2.?! Thanks. Any help welcome.
