I checked this already a while ago, but no that won't help. In
the Java Odyssey discussion I pointed to the Insets method, which
performs an XQueryTree(3X11) to check the window hierarchy.
We need a real parent window which is not the root window.

One ugly trick which comes to my mind is, using a parent window
for all, which is not the root window. This could be a solution,
but I'm not sure about its impacts yet. Will investigate further
during 23c3 into this issue.
