1252 the transient_for hint at all on your window. But people still
1253 use Root, and Kwin is very strange in this regard.
1255 KWin 3.0 will not consider windows with transient_for set to

1257 In that case, it will make them transient for the group. This
1258 leads to all sorts of weird behavior from KDE apps which are
