Subject: [Bug 884564] Re: libnux set a wrong rect region when dual-desktop seta vertical overlap.
@Jay
IMHO, the simplest fix for this issue is attached to use bottom monitor
info to set strut for the panel on bottom monitor. Please check if you
can apply this change. Thx!

Bug description:
I have a 2 monitors and create a external desktop environment, and the external panel stacked vertically above the primary panel. following is some information about xrandr -q
DFP1 disconnected (normal left inverted right x axis y axis)
DFP2 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm
1920x1200 60.0*+
1920x1080 60.0
1600x1200 60.0
DFP5 disconnected (normal left inverted right x axis y axis)
DFP6 connected 1920x1200+0+1200 (normal left inverted right x axis y axis) 582mm x 364mm
1920x1200 60.0*+
1920x1080 60.0
1600x1200 60.0
So the primary panel locate at (0,0) while the external locate at (0,1200), and the unity task bar locate at the bottom of the primary display.
The I want to set the two panel vertical overlapped a small area( reset the position of the external display to(0, 1160) ). use the command: xrandr --output DFP6 --pos 0x1160
The issue observed, and I also found that the issue observed only in the vertical overlap size bigger than the taskbar height(default is 24 pix), if I set the overlap use command: xrandr --output DFP6 --pos 0x1180, every thing is OK.
I have founded the problem in libnux, in the file ./nux-1.14.0/nuxgraphics/XInputWindow.cpp, XInputWindow::SetStruts, line 144
if we set a overlap, and the vertical overlapped size larger than 24 pix, the external monitor information will be skipped to set, and then configure the task bar region a wrong position and a wrong big area. all the window and icons can't move to this area.
In gome2.x there also such problem, you can found the bug in gnome-panel-2.x, https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/884087
