I know of this bug, but was not always able to reproduce it.

This is due to different color depths. You would need to add 32 bit color internally in nxagent everywhere and then do color conversion for the visuals from 32 bit -> source depth.

Yes, I guess its a server side problem. Please do some experiments with testdrive.

Also watch in all your different scenarios, what kind of processes are still running on server. (pstree -p -u nx is helpful here)

And what processes disappear, when you exit a nxssh.exe on Windows.

And if you can get it to work, try also again to setup logging and do a tail -f /var/log/nxserver.log and see what happens again when you kill that nxssh.exe process.

If node.conf is ignored and nxserver.log has the right user (nx) and permissions, you can also change this directly in nxloadconfig.

The steps I've wrote above are the next steps _I_ would try if I could regularly reproduce the problem.
