After upgrading my system this morning and restarting a new gnome-shell session
(by rebooting), everything being displayed fails to repaint properly.
Everytime I launch an application and try to move the window it leaves traces
(i.e., shadows of its previous positions). The same happens on mouse hover.
Also, the clock (on the top desktop) flickers constantly. Something similar
happens with the title bar in certain applications (e.g., vivaldi).
Since the only packages upgraded were related to mutter and gnome-shell, I
figure the one to blame is mutter.

Can you downgrade mutter to 3.21.91-2 (from testing), reboot and test if
the problem is reproducible?
