    Description

      Works fine with KDE desktop with KWin.

      Click in the window with mouse several times. It will move up and down each time.

      In the attached xtrace output we can see that after the window has been unmapped, we get an unexpected configure_notify event:

      000:>:01c6: Event (generated) ConfigureNotify(22) event=0x02a00005 window=0x02a00005 above-sibling=None(0x00000000) x=600 y=526 width=200 height=200 border-width=0 override-redirect=false(0x00)
000:>:01c6: Event ReparentNotify(21) event=0x02a00005 window=0x02a00005 parent=0x0000011b x=600 y=526 override-redirect=false(0x00)

      where 'y' has unexpectedly been changed to 'y=526'. But from the same trace and the attached code we can see that we never requested that kind of position change.
