Sometimes (roughly 50% of the time, but I’m not able to say when exactly), when I resume from suspension, the screen shows for a fraction of second the desktop before suspension, and not the lock screen – which is shown correctly shortly thereafter.
I know it’s not a big deal, but I was curious to know if others have the same behaviour. Although this is mostly safe, it’s not ideal that someone opening up the lid can see (even for a fraction of seconds) the desktop without typing the password.
