Window disapears from desktop switcher

[Ralf]

I have 8 desktops organized in two rows of four. If I open a window on desktop 1 (top row, left), the window is placed in the top left corner of the desktop. Now I move to the top right desktop and the window disappears from the desktop switcher. It only reappears when I move back to desktop 1 or 5 (5=bottom row, left).

The attached picture shows the behavior.

Output of xwininfo for the disappearing window:
xwininfo: Window id: 0x6800504 "~"

Some notes:
- if there is a second window on desktop 1, that is not placed on the left boarder, it does NOT disappear.
- The problem is independent from the program. I reproduced it with gnome-terminal and thunderbird.
- Reproducible for a window on desktop 5.

Environment:
Cairo-Dock: 3.3.2
Ubuntu 12.10
Unity Desktop

Hello and thank you for this bug report! (and sorry for this very very long delay!)

I confirm this bug with Compiz: if a window is on the left border of the first desktop and I switch to the last viewport, Switcher remove this window from the first desktop.

Maybe because Compiz changes some parameters?

@fabounet: what do you think about this bug?
