How to achieve this: 1) Adapt to your setup/needs: [1] 2) Launch VcXsrv on Windows machine 3) launch nxagent session on Linux server 4) Launch KDE4 inside the NX session 5) Launch nxproxy on the windows client as shown by [1] 6) Test if the same issue occurs as observed with X2Go Client I seem to remember that there is some Window-size manipulation code in X2Go Client somewhere when built on MS Win, so that might be obsolete with NX 3.6.
