Keyboard groups, as described here: http://soc.if.usp.br/manual/x11proto-kb-dev/xkbproto.html#Keyboard_State > I somehow doubt that commit caused the problem, though.

As far as I remember, I cannot think of any reason why NIS users should behave different from local users (after all, NIS is just a nameservice like ldap or local files). The only thing that comes to mind is some central configuration that is only pulled in for NIS users. > Roberts home directories are not even coming via NFS so the home dir should be > available at the time nxagent/x2goagent starts and - in that case - tries to > block keyboard file creation by making a directory.

This looks like the app is using OpenGL. Does it work if you disable GLX? > Hopefully that's not a general problem with Qt5 applications? Well, it depends on the standard (system) configuration for Qt apps. It Qt is configured to use OpenGL most apps will suffer from this.
