Subject: Bug#1006: Slow refresh with Chrome/Chromium

Package: x2goserver
Version: 4.0.5.0 

Context : x2goserver 4.0.5.0 on Ubuntu Mate 14.04 with x2go stable ppa in MATE Desktop mode.

Chrome and Chromium's refresh is painfully slow with x2go while Firefox is a lot smoother.
Most applications, even graphical intensive such as Gimp are working very smoohtly too, only Chrome/Chromium is really really slow.

Is there something that might be done on the x2go side ?
Maybe some custom options to use within Chrome/Chromium ?

With ps, here is the command line used with my chromium instance (default settings, nothing has been tuned) :

ps aux | grep chromium
walid    24977  2.4  8.0 1192724 163960 ?      Sl   09:42   0:01 chromium-browser --enable-pinch                          
walid    24988  1.3  3.3 657324 69196 ?        S    09:42   0:00 chromium-browser --type=zygote                          
walid    24990  0.0  0.6 657324 13360 ?        S    09:42   0:00 chromium-browser --type=zygote                          
walid    25032  2.7  5.8 1413712 118996 ?      Sl   09:42   0:01 /usr/lib/chromium-browser/chro                          
walid    25115  0.0  0.1  15208  2144 pts/0    S+   09:43   0:00 grep --color=auto chromium

Chrome/Chromium enables HW acceleration by default, I tried to disable it in order to see if that helps but it changed nothing.

Best regards,
