[Bug 1459899] [NEW] 1-10s delay to screen lock when coming out of suspend/hibernate

 

*** This bug is a security vulnerability ***

Public security bug reported:

My laptop is set to lock and require my password after resuming from
sleep.  If I close my laptop screen (thereby inducing a sleep state) and
open it back up again, there's a significant delay (1-10 seconds!)
before the lock screen appears, and it seems like the delay depends on
the amount of RAM in use. During that delay, not only is everything on
the screen visible, but also the end user can still interact with
everything!  It's a pretty jarring security issue.

I've been experiencing this issue since v13, but haven't minded much
until recently since the delays have become much worse (might just be
due to my laptop aging though.)
