(In my co-worker's computer it's something deeper than the desktop environment that causes these slow updates. Both Unity and XFCE in his laptop have these slow updates.)
Any ideas what could be causing the slow updates on the terminal windows?
When my co-worker has for example two single windows opened from a x2go session and he moves one, it takes up to 10 seconds for the other window to update its contents, if the windows were on top of each other. You can see a white area that is slowly drawn to update the window contents.
Looks like the bug #1010 http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1010 talks about the same problem my co-worker is experiencing.
I'm using KDE on Kubuntu 14.04 and I only get a short white flash on the window below when its contents are updated. We're using the same x2go server.
I tested different desktop environments and X2Go client's single application mode with two windows opened from the X2GO server.
Desktop environments that have fast window update speed:
- kde and lxde
Desktop environments that have slow window update speed:
- unity, xfce and mate
I'm open to any suggestions on how to test and fix this problem.
I realized that I've been not so clear about this report that I could have.
The desktop environments that I tested previously were on the client machine.
On the X2Go server I have XFCE installed and when using the single application mode, I run XFCE's /usr/bin/Terminal as the application.
Single application mode on the Windows X2Go client also works fine.
The window updates when moving two windows on top of each other are as fast as on kde and lxde.
