This bug report got missed because it was logged in the wrong category.
Graphical issues relating to the login and lock screens are still gnome-
shell issues.
The problem was mainly discussed in bug 1532508. Then bug 1768786 was
opened and it was declared fixed for gnome-shell version
3.28.2-0ubuntu0.18.04.1. Please comment in one of those bugs if you feel
the fix isn't working.

Title:
when screen is locked and I open my laptop, a past screen is flashed
Status in gdm package in Ubuntu:
New
Status in gnome-screensaver package in Ubuntu:
Confirmed
Bug description:
I close my laptop, which locks the screen. I then open the laptop.
Sometimes I must hit the power button to get the screen to unlock. But
before I see the password prompt, I see something else.
I see a past random screen. It goes by quickly, in less than a second.
But this is still not acceptable. The screen should not show _any_
information before the user has logged in.
It would not be bad if I could somehow determine what this screen is,
because then I would make sure it is blank. But it seems random.
Sometimes it seems to be the screen I had visible when I closed up the
laptop. Sometimes it seems to be the screen I had visible at one of
the last several times I closed the laptop. It does not seem very
deterministic. It is hard to know which screen it is going to flash at
me before the password prompt.
