Matlab Gui compatibility - Different aspects between Linux and MacOS

I have a problem of compatibility between Linux and MacOS with a Matlab Gui. The graphical interface is developped under Linux Debian 7.0. Here's the aspect on this platform :

Now, I execute the .m file on MacOS and here's the result :

As you can see, the panel (the box where there are the 3 disks on the first figure (sorry, the 3 disks doesn't appear on the second)) and, more globally, the figure on MacOS 10.9.5 is stretched horizontally, i.e the window is wider than high.

I tried to change Units (tried with characters, normalized, pixels) but nothing does it.

it does not bother me to have a different font for "edit" boxes and buttons but I would like to have the same size ratio under both OS for the panel, i.e to have a square panel like under Linux Matlab.

If someone could help me, this would be nice

Thanks

ps: I put in attachment the .fig and .m file (gui_dev.fig and gui_dev_export.m)
