Thank you Antoine for your quick answer.
I am running xpra-1.0-0.20161013r14149. XPRA server and Xapp are running on Centos 7.2 and XPRA client is running on Fedora. At this time of writing, no new beta available on Winswitch.org repository.
Here are the logs from the client with -d printing option:
