Setting padding to 0 doesn't actually set padding/margin to 0

I have the same problem, it seens xterm-screen has the wrong size.
I would like to be able to set the padding all to zero. It is not feeling good to have large padding by default. I realized the top and left padding could be set to zero but the right and bottom has some default padding values that could not be override.
I am in Linux 18.
