Comment 18 for bug 576751

Reading the report at https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/17787 might give a clue to the source of the problem. The real culprit seems to be the transparency of the panel. The panel with the wnck-applet needs to have both auto-hide and transparency enabled for the memory leak to show up (I just checked now, even if auto-hide is off and only transparency is enabled, switching workspaces causes a leak). After disabling transparency by changing the panel background to None (but keeping auto-hide enabled), I am no longer seeing the memory leak on my system. Can others confirm if they are seeing similar results?
