I tried it on Linux Mint (which uses the Gnome desktop) on my HP Mini 
notebook computer.

It appears to work the same there, with a few minor differences.

When I tried to move the Firefox window using the alt-click-drag method, 
it worked, but it first re-sized the window to where it didn't fill up 
the whole screen.  The alt-click-drag method of moving the window worked.

I could move the Synaptic Package Manager window using the 
alt-click-drag method.

My application behaved the same way as on Lubuntu.  Per my fix, I 
display the window in its minimum vertical dimensions, which was still 
too large for the screen, but better than before.  I could move the 
window around using the alt-click-drag method.

There was one notable difference I noticed.  The "maximize window" 
button was not on the title-bar.  There was still a "minimize (iconify) 
window" button, but no "maximize window" button.  Also, the Java/Swing 
function-key (F11) to make the current window full-screen had no effect.
