I just noticed that as well. On linux it works a lot less stable. Aka,
i have to start the application about 10x before i finally see one
where the shader effects (DropShadow in this case) are applied.

Also note that you might have a "sort of shadow". It is by no means a
shadow. It's just a "copy" of the rectangle in the color set in
DropShadow. The actual shadow effect (smooth blurred grey.. don't
really know how to call it) isn't applied.
