Your issue is related to changing the theme.

If I use the default theme of Fedora 22 I don't get the blinking notification.

If I install xfce-theme-manager and select an alternate theme I see the issue you're experiencing.

FWIW, if you do a google search on "xfce blinking taskbar" you'll see others have the same complaint.

I've not found a way to disable it as of yet.
