GNOME Bugzilla – Bug 601805
Invest applet's dropdown window leaves a shadow after closing

I click on the applet icon on the panel, the stock list opens, then I close it, and the compiz-generated drop shadow is still there. The only way to get rid of it is to remove the applet from the panel.
This is a problem with the compiz package, which has been fixed, see https://bugs.launchpad.net/ubuntu/+source/gnome-applets/+bug/449272
