Hi,
I use Linphone as a SIP phone for VoIP use in our TCE setup. It works very well but sometimes, the application freezes, the GUI becomes grey and the desktop behaves strangely (windows don't refresh properly, most of the desktop is practicaly unusable). The session doesn't crash and the freeze last from a few seconds to 2-3 minutes sometimes. Doing nothing and waiting gently fix the issue and everything gets back to normal after that until the next occurence.
It's pretty annoying for my users because we're a call center and it happens randomly a few times a day.
When it happens, I get this in the $HOME/.xsession-x2go-server-errors
====================================================================== Window Manager Warning : Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1c0003a (Linphone) Window Manager Warning : meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
Any idea ? Is this something that needs to be fixed on the X2Go side, the MATE side (I'm using MATE Desktop) or on the application side ?

Well, to rule out X2Go, you could try replacing one of your ThinClients with a local MATE + LinPhone installation and see if LinPhone acts up there as well. Also, what happens if you try to use a different SIP client?

Well, this is not only Linphone in fact ...
I get some new (apparently related) bug here. This time, it is easily reproducible :
Within your X2Go session :
- on MATE Desktop (tried with both 1.12 which is shipped with Ubuntu 16.04 and 1.16 from the PPA repo), open Chromium browser maximized
- then open another smaller window, might be Caja or anything else (tried Linphone, VLC, Pluma, ...), the window opens in front of the Chromium window
- click on the chromium window to bring it to the front
- try to bring the window behind to the front by clicking in the task panel at the bottom of the screen ... the button blink but the window don't come to the front (Chromium stay in front)
- only way to make it visible is to minimize Chromium
When you do that, you get that message in .xsession-errors :
Avertissement du gestionnaire de fenêtres : last_user_time (1517931) is greater than comparison timestamp (2416812277). This most likely represents a buggy client sending inaccurate timestamps in messages such as _NET_ACTIVE_WINDOW. Trying to work around... Avertissement du gestionnaire de fenêtres : 0x2800001 (Google –) appears to be one of the offending windows with a timestamp of 1517931. Working around...

Ok, I answer myself because I found a workaround for this specific example ... This problem occured after updating Chromium to v56. This is this specific release that has this problem for windows depth ordering. I downgraded to the previous release available in the repo (v49) and it fixed the problem.
So by now, I'm ok with it, I'll try the next release to see if this is going to be fixed. Anyway, this problem with this version occures only with X2Go, I had no problem with a local computer so I don't know if this is a "normal behaviour which is faulty on my X2Go environment" or if this is a bug in Chromium.
So ok for Chromium but I still have freezes issues with Linphone and I still don't really know who is faulty (X2Go or any of its dependencies, Linphone itself, MATE desktop, ...) so, sorry if it is definitely not X2Go but since this problem only occures on my TCEs, I thought I could post this here.
