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).

1) 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.

2) 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.

defaults): MATE desktop: enabled BIG-REQUESTS
