Package: x2goclient Version: 4.1.2.0
I'm using x2goclient 4.1.2.0 on Windows 10. I have found two ways that break the bidirectional clipboard mode, one for the MATE desktop and one for the Plasma 4 desktop (both on the x2go server).
- MATE desktop
Open a connection to your x2go server.
In Windows 10: Open a text editor. I use Notepad++.
- Write a single character in the editor, then select it and use copy.
In MATE desktop: Open a text editor. I use pluma.
- Press spacebar once and then select the empty space with ctrl+a.
- Use paste to paste the clipboard contents. At this point the clipboard functionality breaks.
- Plasma 4 desktop
Open a connection to your x2go server.
In Windows 10: Open a text editor. I use Notepad++.
- Write a single character in the editor, then select it and use copy.
In Plasma 4 desktop: Open a text editor. I use emacs. If I use KWrite there is no problem.
- In an empty emacs buffer, press spacebar once, press cursor left and then use ctrl+space to mark the selection starting point and press cursor right once to select the empty space.
- Use ctrl+y to yank the contents of the clipboard. At this point the clipboard functionality breaks and emacs goes into a loop consuming 100% CPU.
Both of these break the Windows 10 side clipboard so that it doesn't work until I restart the computer.

Thanks! This sounds a bit like a off-by-one problem in the clipboard code.
However, to break this down further I want to rule out some components. First, can you please verify if this is somehow reproducable on a Linux client?
Next I would like to try and take x2go out of the equation:
- run vcxsrv on windows (vcxsrv.exe -multiwindow -ac :121)
- ssh to the Linux server (e.g. with putty) and point the DISPLAY variable to the VcXsrv on windows (export DISPLAY=:<windowsmachine>:121) Note: you might have to disable the windows firewall
- run nxagent -ac :123 in the shell on the server -> you will get the nxagent window on you Windows desktop
- in a second shell on the server point the DISPLAY variable to :123 and start the MATE session (export DISPLAY=:123; STARTUP=mate-session dbus-run-session /etc/X11/Xsession) Now repeat your editor tests.

The bidirectional clipboard mode doesn't break with the Linux x2goclient, in either MATE desktop or Plasma 4 desktop. I'm using x2goclient v4.1.1.1 on Fedora 27 client machine.
Next I would like to try and take x2go out of the equation:
- run vcxsrv on windows (vcxsrv.exe -multiwindow -ac :121)
- ssh to the Linux server (e.g. with putty) and point the DISPLAY variable to the VcXsrv on windows (export DISPLAY=:<windowsmachine>:121) Note: you might have to disable the windows firewall
- run nxagent -ac :123 in the shell on the server -> you will get the nxagent window on you Windows desktop
- in a second shell on the server point the DISPLAY variable to :123 and start the MATE session (export DISPLAY=:123; STARTUP=mate-session dbus-run-session /etc/X11/Xsession) Now repeat your editor tests.

I used PuTTY's X11 forwarding/tunneling to do this. The bidirectional clipboard mode breaks in the same way with this method in both MATE desktop and Plasma 4 desktop.

I tested x2goclient with mobaxterm too. With it the bidirectional clipboard mode keeps on working, it just doesn't support that case that you've selected a single space in your x2go server's text editor and try to paste on top of it.
I tested this in Windows 8 and there was no rdpclip.exe process running.
