I've just noticed that having sticky notes active on the desktop will cause Guake to act irregularly (as described above). Redocking the sticky notes solves the issue. The sticky note applet is like an on/off switch for this bug. (This is only the case with compiz enabled). With Compiz disabled, Guake will behave as expected with or without sticky notes on the desktop. Hope this observation can shed light on the situation. It is a rather erratic bug.
