Bug Description

I'm using current Ubuntu Gnome 16.04.2 but the same issue is present in Ubuntu 16.04.2.

The problem occurs with or without nvidia drivers. I'm running a fresh installation.

On resume, for a second, i can see my screen as it was before suspend. This means that if someone open my laptop can see my desktop and my things.

Ok is only a second, but is a very hight security issue for me.

I'm sure that is not an hardware problem because with Kde Neon I have not the same behaviour , with or without nvidia drivers.

Experiencing this on 17.10. It happens on every resume from suspend.

Distributor ID: Ubuntu
Description: Ubuntu 17.10

I am using gnome-session, Xorg, and gdm3.

Is this the same as Bug #1416897?
