If you have *a lot* of desktop icons and drag them all, the current code (using
a mask and no ARGB window) makes kwin so slow, that the automatic desktop
effects deactivation kicks in. So I think just for that it is worth to apply
this (or a similar) patch. Also I think using these masked icons are really
ugly. If no ARGB window can be used it would be better to use drag icons like
dolphin does.
