while this long standing problem has been mitigated with some previous work and patches (eg: #389519) at least keeping the mouse away from the dead area, the desktop behaviour if far from being precise still.
when using a couple of monitors with different vertical resolution, icons can easily get lost on the shortest monitor, to reproduce the bug just put on the shortest monitor enough icons to exceed a single column, click on the desktop with the right mouse button and then "organize desktop by name".
another issue is with compiz corner hotspots bindings, they are never triggered if there's a dead area above or below theme, it depends on where your shortest display is aligned in respect of the tallest (top or bottom margin), to reproduce try for example to bind the "Show Desktop" action on a corner of the shortest display.
