--- Comment #3 from kotipalvelu at hotmail.com ---
I can confirm this is happening still with 4.4 kernel pulled from Ubuntu kernel
-site (Trusty 14.04 with 4.4).

I switched desktop users between Ubuntu Unity (Compiz) desktop and
gnome-flashback desktop user, switching from compiz to flashback went OK byt
switching back triggers this (tried twice):
