Public bug reported:
After hibernate the PC, the desktop wallpaper become all pixelized, not
just desktop but windows edges too: all around every window I open there
is a pixelized bound. In the windows I open after the resume, the
buttons to close, minimize/maximize, ... are big pixels. This started
after I finished some system updates. Only after reboot everything
returns ok. I have Ubuntu 16.10 on the PC.
