But kwin has much trouble with multi screen systems. It can't scale images
across two or more monitors and has a bugs in calculating the window size -
i.e. minimize and maximize a windows shows holes in the window borders.
Hope, that multi screen will be tested exentsive than the bugs in KDE4 in this
area stops me using it.
