If all of the windows shown on desktop (active windows) are set as 'always on
top',
GetTopMostValidWindowInViewport() will be Desktop but not any of the active
windows.
This could explain the phenomenon noted in the comment #9:
'if there are two windows set as Always onTop, this bug could be
in
unity-shared/PluginAdapter.cpp
621 if (window-defaultViewport() == screen_vp
622 window-isViewable() window-isMapped()
623 !window-minimized() !window-inShowDesktopMode()
624 !(window-state() CompWindowStateAboveMask)
625 !(window-type()
the two numbers I mentioned in comment #13, I meant:
window-state() = (unsigned int ) @0x186e480: 8192
window-state() = (unsigned int ) @0x186e480: 8704

namely the two variables active and scaleWasActive are false.
A window which set as Always on Top make wm.IsWindowOnTop(xid) return false,
and this make any_on_top keep false.
Finally active will be set as false.

why does wm.IsWindowOnTop(xid) return false when the window is set as
Always on Top
this is because GetTopMostValidWindowInViewport() does not return the
xid which is equal to the Always on Top window.
please see unity-shared/PluginAdapter.cpp:604
unity::PluginAdapter::IsWindowOnTop
looks like the name of the top window is Desktop in comment 10 instead
of the name of the real always on top window.

1. launch two calculator applications, say A and B
2. set A as Always on top, and make B minimized
3. try to use application spread, then you will reproduce this bug
4. minimized A
5. use application spread again. only A pop up.

Also the fix for this will be in unity/unity-shared/PluignAdapter.cpp.
Where we tell if a window is on top. What is happening, is we skip
always on top windows and if all the other windows are minimized it will
return false.
