I see to have the same problem on  x2goclient v4.0.2.1, running on Macosx/Yosemite causes high cpu on server
Desktop used LXDE, connection works fine but the openbox executable uses lots of cpu.
Running x2goclient on Window/Linux has no problem using the same server.

Seems to be keyboard related, strace of the openbox process shows lots of:
