Oh! A man who understands KSelectionWatcher! I need your help. Could you look into KSelectionWatcher in \
the kdelibs-frameworks branch (with Qt5 installed), and port the kselectionwatcher unittest to the new \
kselectionwatcher API (fredrikh made it async, due to XCB being async, but didn't port the unittest)?

Technically:
I do not at all understand why KWindowSystem is *not* watching the root window - KSelectionOwner for one \
is sending events to the root and this also seems the case for all other WMs (at least everything now \
starts to cause the signal to be emitted)

As for SubstructureNotify, well, the message is sent to the root window - but the iccm suggests to send \
by StructureNotify mask (http://tronche.com/gui/x/icccm/sec-2.html) bottom of the page. I just gave it a \
wild shot (&quot;hey, what if we tell everyone&quot;) and it absolutely reproducibly enables notification \
of selectionwatcher constructed before the eventloop is up (while it also very much seems to be not \
required once the eventloop is actually up) and i don&#39;t think it should hurt at all (but might hint a \
problem in rather the selectionwatcher, since we cannot expect others to send by that mask)</pre>  </td>
