Version: (using KDE 4.1.2) Installed from: Ubuntu Packages Description: Always on top apps cast border shadows on menus. To reproduce: Open any window and set it to "Keep above others". Now place it in such a way that its border lies on the KMenu area. Now click on the K-Menu and you will see the shadow of the window (see attachment)
