Same here. I just installed the latest x2go client stable release version 4.0.3.0 and the window border disappears along with the minimize, maximize and close buttons when pressing the maximize button. Moving the window has no strage effect, though.
Client: Windows 7 32-bit SP1
Package: x2goclient
Version: 4.0.3.0
Host: Linux Mint 17 64 bit
x2goserver: 4.0.1.18-0~949~ubuntu14.04.1
x2goagent: 2:3.5.0.28-0~481~ubuntu14.04.1
nxagent: 2:3.5.0.28-0~481~ubuntu14.04.1
Here are the requested output before and after maximizing the window and losing the window controls:
