The phenomenon leads from overwhelming special effects of xfce.
One can shutdown it by clicking Application (at the top left corner of the x2go windows), Settings, Settings Manager, Window Manager Tweaks, Compositor. Then unselect the option Enable display compositing.
If the performance is so bad that you can not open any windows, you can log in the server through ssh. Then open file ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml, find the line including use_compositing and change value true to false. This is Linux~ (Remember to terminate the x2go session using x2go client's button terminate, instead of just closing the x2go windows!!!)
