Not sure if this is possible with KDE, but for those with overscan problems on their desktops like me, here a little workaround to make it less annoying:
Create 4 new panels. Place each panel on the top, bottom, left and right sides of the screen. Make each panel's background color black (color code #000000) with 0 transparency. Then adjust the size of each panel so that it's right at the edge of your screen.
This way, you can maximize windows and the edges of those windows aren't out of view. The panels will effectively "restrict" the size of your desktop to a size you set. Obviously, this does nothing for media managers that use full screen and have their own settings for desktop edges, but this seems to work ok for when you're not in a media center application.
Hope this helps.
