Hmm - I just "played" a bit with the Qt example app "windowflags" (this is
with Qt5.0.1), and
observed the following:

 I can change the "Window stays on bottom" flag and the window moves down the
z-axis. Swiching of
 the flag the window moves up again. This works repeatedly. But as soon as I
change the window type
 to something other than "Window" ('dialog' for example) the window gets stuck
on the top level.
 Changing back to type 'windows' does _not_ solve the problem. Once the window
has been a 'dialog'
 or similar, any changes to the NetWMState seem to be ignored.

 BTW, everytime a property gets changed, the windows moves down the screen ....
