Comment 7 for bug 756689

I also have this problem happening, although it usually seems to be repeating the bottom half of my unity launcher, after a certain random application each time. This is especially bothersome when I cannot just close or reopen the afflicted applications because it would affect their operation. Perfect example is right now as I am FTP'ing important files, yet my FTP client (Filezilla) has multiple instances duplicating in the unity launcher and I am afraid this will compromise either my computer or the applications performance.
