** Description changed: X11 forwarding slows down Ubuntu 16.04 with Unity desktop whose whole graphic interface (including mouse pointer) repeatedly becomes unresponsive for seconds if `ssh -X` or `ssh -X -C` is used. The symptoms are the same as if the system were using slow swap space which isn't the case (verified with `htop` in another tty which can still be changed). This wasn't the case in previous unknown versions. - experienced with 1:6.9p1-2ubuntu0.1 on Ubuntu 15.10, + experienced with client versions 1:6.9p1-2ubuntu0.1 on Ubuntu 15.10, V_7_1_P1-171-g4c6cb83 source installation and 1:7.2p2-4 on Ubuntu 16.04 + with `openssh-server` 1:7.2p2-4 on Ubuntu 16.04 on the server side.
