Public bug reported:

Binary package hint: compiz

I'm using Ubuntu 8.10 with extra visual effects, and "Place Windows"
setting is checked in compizconfig setting manager.

I notice top-level window will be moved to other workspace by
gdk_window_show/gdk_window_raise/gdk_window_deiconify if the window is
partly out of the workspace.

If I unchecked "Place Windows" in compizconfig setting manager, the
window will not be moved by above function call.

The description of "Place Windows" is: Place windows at appropriate
positions when mapped. Since the window has been mapped, why move it
again?

The sample code is below. When  GDK_BUTTON_PRESS is received,
gdk_window_show will be called.

Steps to reproduce the bug:
1. move the window partly out of the workspace
2. click it(not titlebar)
bug: the window is moved to another workspace.
