...first, compare your initial console output with the one (:sigh:) on the screenshot - it might be something like using a lower resolution.
Other potential option is that this is a Mesa/hardware difference - perhaps one of you is using integrated card while other is not and that either make a memory consumption different on its own or the driver does something differently resulting in the consumption difference.
