I should have probably mentioned that this lag also occurs when running the X2Go client directly on the server itself, so it doesn't seem to be an issue with the WAN link, Windows 10, etc. For the sake of comparison I ran Firefox 48.0 via X2Go on another machine on the same 100Mbit LAN as the server, then ran it again in a forwarded X11 SSH session (compression enabled); the latter demonstrated no noticeable lag while the X2Go session struggled to keep up.
