Window Snap causes weird mouse cursor position

[Sven Romeike]

When I use the Window Snap Function in Unity to have 2 applications maximize to half of the screen and restore them again by draging one of the windows back to the middle the mouse cursor is moved way to high above the titlebar when the snap mode ends.

to reproduce this use the following steps:

1) start unity
2) start a random application and pin it to one edge of the screen
3) remove the snap mode window from the screen edge by draging it back to the middle

the mouse cursor will be way to high above the window. It's not only Graphical as you also feel the the window is "under" the mousecursor which feels weird. you got to stop draging and start draging again to have everything back to normal.

This is probably a Compiz bug but ubuntu-bug did not find any duplicates yet.
