I have noticed that often when I awake my machine from suspend that on the locked screen although I can still use the cursor to do things, it is not actually visible, though it comes back into visibility once I have logged in. This mostly occurs after I experience this bug #1588521, however this is not always the case. I am running Ubuntu GNOME 16.04.1 with GNOME 3.20.
