Simply set the windowshape to noe again and you can examine the stack.
There is an image "wtest1.png" that I created in Photoshop.

Yes! It is completely tranparent except for the rects where the

Yes, see above.

Sorry, I have no idea. As Ian said this is probably an OS dependant  
"feature"
but should not happen at all in my opinion.
