When I change the language on lock screen with keyboard shortcut, the system freezes for a few seconds, the lock screen disappears (I haven't typed a password), for fraction of a second I see all my windows and then the lock screen appears again.
I can recreate this every time (on two clean Ubuntu installations with the latest updates), but it happens only if I use the keyboard shortcuts. Everything is fine if I change the language from the top menu.
Anyone else with the same problem?

. The problem started after latestcompiz
upgrade tocompiz:amd64 (1:0.9.12.2+16.04.20160526-0ubuntu1, 1:0.9.12.2+16.04.20160714-0ubuntu1)
. So we can try to downgrade it, but I didn't test it yet.
