I am experiencing the same bug. This makes the "Application Switcher" plugin very annoying. As with others, the switcher is centered on initial use and after some (unknown, TBD) time, it does a "jump" when used. When jumpy, it first appears to be centered for a fraction of a second, then moves diagonally, off center. The magnitude of the shift seems to be variable (though always increasing). I have no information on direction yet.
Regarding "evilregis"'s comment: You are correct that simply disabling and then re-enabling that specific plugin ("Application Switcher" in the CompizConfig Settings Manager) restores the correct centering behavior of the switcher. When the shift becomes too far off, after hours of time on the machine, I disable and then re-enable the plugin. See elsewhere for how to install this extra software, it's easy, and when done, you have access to a sort of control panel found in the menus: System-->Preferences-->Advanced Desktop Effect Settings, as well as through the original, "Appearence" preferences applet. I will try the switcher after performing certain window management tasks, such as maximize, minimize, unmaximize, full-screen, etc. to look for events that initiate the jump. I guess that there's something that accidentally adds to the shift every time it's done (therefore starting at "0" magnitude and monotonically increasing thereafter). Just a hunch, though I have not touched the code at all. Hope this helps.
