We are experiencing a strange bug in the interplay of x2go with a
component of the ROOT data analysis framework
(https://root.cern.ch). Displaying GUI windows in the ROOT
framework, shows them shortly and results in an immediate CRASH of
the X2go connection with a Windows error "vcxsrv.exe has stopped
working" and subsequent closure of all opened remote applications. Strangely the GUI window shows up when resuming the session in X2go.
Running the ROOT GUI window from pure vcxsrv, Xming, Mobaxfire or
similar Windows X-Server applications works flawlessly. It also
worked previously with the "baikal" version of X2go. I admit this
seems to be an exotic bug but there might be further graphical
software affected which increases the severity of this bug.Steps to reproduce:
- Install ROOT from the webpage or via "apt-get install
root-system-bin" on the x2goserver- Run "root" on command line.
- Open a TBrowser with the command "TBrowser b"
After this the x2goclient slowly fills the "session" log with warnings of "Proxy: WARNING! Handling data for finishing FD#6 channel ID#1."
This bug is a kind of a show stopper for us because we need ROOT for
scientific use. I would help to further track down the error and
debug if I can get some hints where and how to start.Kind regards, Martin
Is it possible to be granted access to a reference installation that
shows the above describe behaviour?
Esp. the fact, that resuming the "crashed" session gives me a bit of
hope here.
Also: do you know if your software uses the X11 bigrequests extension?
Thanks+Greets, Mike
