Compiz application switcher isn't centered

Screenshot of problem. In this capture, there were only a few applications open. However, with additional applications, the switcher slides off the screen.

Apologies, left the extension off of the screenshot. Here's a corrected version.

I confirm this thing here on my Acer Aspire 5680 Laptop.
The application switcher window goes to the left and a bit down, for me, just a bit after it shows.
It doesn't happen always but, when this behaviour begins, it doesn't end until compiz is restarted.

I forgot, I have Ubuntu Gutsy, with the included compiz-fusion.

This is happening as well on my HP dv9000. It happens to varying degrees as far as the offset goes. I just log off and back on to fix the problem. Next time it happens I am going to try disabling that plugin and re-enabling to see if that does anything to fix it... save me having to log out and close everything I'm working on.

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. Thanks!!

I can confirm this on my Acer 3690 (Intel chipset) in Gutsy. It starts out in the center, then jumps maybe 150px to the right and a few pixels down when the full border is drawn. (That is, it starts with the white background but not a well defined border, then jumps and draws the background and border.) I've had this problem since Beryl/Feisty.

This seems to be an intermediate problems for me as well.
