Subject: shadow sessions inside nxagent sessions fail

Date: Wed, 18 Mar 2015 16:10:54 +0000

[Message part 1 (text/plain, inline)]

Package: nxagent
Severity: important
Version: 3.5.0.29
Control: forwarded -1 https://github.com/ArcticaProject/nx-libs/issues/6

We just tried to run cascaded sessions with one of them being a  
desktop sharing session:

(a) from client (host-A) launch X2Go session to a remote server (server-B)
(b) from X2Go session on server-B launch a remote desktop sharing  
session with :0 on remote
host-C

Result: a black nxagent window appears (inside the X2Go Session on  
server-B) that accepts mouse and keyboard input (which both arrive on  
host-C via desktop sharing). If I manage to move a window via the  
desktop sharing session, the black nxagent window does some screen  
updates, but no full view of the remotely shared desktop appears.

Further discussion see: https://github.com/ArcticaProject/nx-libs/issues/6

Just for the record, this issue is resolved on the 3.6.x branch. We  
solved it by building nxagent against X.Org libXdamage.

The fix for this issue is not easily backportabled to 3.5.x.

Greets,
