Good news, the problem disappeared after upgrade to 16.04 (lots of other system bugs appeared however). Now I can reliably connect via remmina with vnc and xrdp with no tweaks at all. However it does pop up with an irritating message with every connection saying the certificate has changed and I have to click OK. But I can live with that now that everything else works on remmina.
