Comment 5 for bug 340895

I think I am experiencing the same thing. In a 64bit jaunty installation. I cannot move any windows they all open and stay in the top left corner. Alt + tab does not work. All the borders are gone so windows cannot be resized, minimized or maximized. I am able to switch between windows from the window list on my panel although once briefly windows did not show up there either.

All this goes away if visual effects are set to none. Once when setting visual effects to normal I was logged out.

I have an integrated intel x3100 graphics card GMA965. In the past there have been many problems with this card and compiz/any graphics.

This started with an update in jaunty to compiz (I actually think the old compiz package was removed and a differently named one installed) a few days ago around when this bug was filed.
