But both CentOS 7 with GNOME 3.8, Fedora 20 with GNOME 3.10 and Fedora 21 
with GNOME 3.14 tell us that GNOME 3 itself can work well with xrdp without 
any issues and this is a Debian ONLY bug. You can try them as well. And maybe
you can find the difference of xrdp between Debian and those Red Hat based
OS and find how they overcome this issue. If you need any more information,
I would like to help.
