[X2Go-User] screen redraw/flickering issue on Mac OS client

[Jeff]

Hello,

I've had great success with using x2go using Debian as client and
server.

I'm experiencing an issue with the Mac client (v4.0.2.1) connecting to a
Debian server (4.0.1.16-0x2go1+git20140926.935+jessie.main.1). I'm using
XQuartz (2.7.7) in full screen mode on Mavericks. Every few seconds, the
screen will drastically flicker, as if redrawing the entire screen, or
as if X is very quickly switching back and forth between windows or
something. It seems to happen more frequently when I am doing a lot of
mouse/keyboard activity, although it does also happen if I stop and let
the screen just sit there.

Any ideas what might be causing this, or what options I might try to
tweak to get rid of this issue? It's distracting enough that it really
prevents normal usage.

Thanks!
Jeff
