Comment 18 for bug 898870

I noticed that the degree to which the overlap is present on the next workspace is based on the width of the window borders listed in the user's theme. I edited the metacity-theme-1.xml file for my theme to resolve this problem. Simply go to the section of the file listing <frame_geometry name="frame_geometry_normal" ... > and underneath that, set left_width and right_width to 0 (set bottom_height to zero for visual consistency). This gets rid of the overhang, but I think the shadow is still present in the adjacent workspace. Setting the width to anything other than zero leads to an overhang that is twice that width on the next workspace.
