Hi all,
Thanks for the answers. @Stefan: The problem occurs in both modes. (We used X2Go in desktop mode for a long time before trying single-application mode, no difference). Adding *-Dsun.java2d.xrender=True* did improve latency (although it's noticeable, so I'd like to investigate more).
@Ulrich The environment variable did not change anything, but maybe the second one will (that recommendation is from 2012).

If you are using the single application mode you could try this:

This makes me wonder - in your initial post to the list, you stated you were using XFCE. Now it sounds like you're trying to use single application mode.
If you're only seeing this issue in seamless modes like single or published application mode, then I'm not too surprised. I think one of our devs - could have been Mihai, so cc'ing him here - once mentioned that "refreshing" doesn't work as well there. And IIRC, Java GUI applications like Eclipse were always quite laggy from an NX-libs point of view. Uli's suggestion re: disabling 3D rendering is also worth trying.
@Mihai: Was this something about XDamage only working with Desktop Environments?
@Tom: You could also try out a Linux client (boot a live Linux via USB if you have no other option) and see if X2GoClient on Linux behaves the same way, or if the situation is better there - maybe X2GoClient / VcXsrv on Windows are being "hassled" by a virus scanner you have running, while the NoMachine App is whitelisted (e.g. by being cryptographically signed by NoMachine)?
If it's not too much of a problem for you, you could also try out upgrading your server to the development version of X2GoServer and try running X2Go in KDrive mode (this only works for Desktop Environments, not for single/published applications, though).
