It has been reported that Ubuntu 14.04 does not work well with MSEide+MSEgui
http://sourceforge.net/projects/mseide-msegui/
(a cross platform GUI development environment).
The window positions are wrong, especially by maximizing and normalizing back a window. I absolutely don't know Ubuntu; I made a default installation and could reproduce the problem. A first investigation shows that the window-manager seems not to respect the wm hint wingravity = static_gravity in xconfigurewindow() call. Instead to place the client area at the wanted position it uses the top-left corner of the decoration window. The program
