Desktop Cube: Unity's top panel shadow gets deformed also and rendered on the desktop cube instead of sticking with the top panel when the cube gets activated

Bug Description

The shadow of the main Unity panel on top should stay untouched, like the panel does, when using the desktop cube, instead of being rendered onto the cube.
The situation gets even worse visually when "Cube Reflection and Deformation" is used additionally, because now the shadow does not deform with the cube, but stays in the same position of the original cube.

Ubuntu 12.04, Compiz 0.9.7.8-0ubuntu1vvpreproposed2

Shadow of Unity's Top Panel sticks with desktop background instead of staying static like the panel itsel does (Screenshot shows Unfolding the Cube look) Edit (303.8 KiB, image/png)

I attached a screenshot showing the Unity Top Panel Shadow being rendered onto the face of the unfolded cube.

I suspect unity should be checking the paint mask and not drawing the panel shadow is the screen is transformed. However I also suspect the expo plugin is failing to set the screen transformed flag, based on other work I've done this week.

I am going to set it as confirmed since its clearly an issue. As we are not sure if its actually a bug in unity feel free to set it back to NEW.

Replace /usr/share/unity/3/panel-shadow.png with an invisible image.

I do not want to eliminate the panel-shadow completely, but I might do that, because the shadow showing everywhere (Stack Switcher, Cube, etc.) is making things really ugly.
mnrl, thanks for pointing to a possible workaround, I did not think about the shadow being a simple texture one could simply make transparent :)

I think we might have fixed this with bug 1012956.

Daniel, I got Compiz 1:0.9.8+bzr3249+bzr3278ubuntu0+3273 installed, but the shadow is still rendered on the cube and stack switcher...
