I noticed an odd issue with sleep/suspend. I am not sure if its been mentioned before, and it might be an upstream issue.
If I have any popover open (app menu, quicknote, etc… doesn’t matter which), leave the popover open, shut the lid on my laptop and wait a few seconds, my laptop suspends. When I open the lid back up, the popover is still there. If I wait a few seconds without touching anything, I can continue to use my laptop without the lock screen ever coming up.
Now, similar situation… I leave a popover open, shut the lid to suspend it, and open it back up to resume. Again, the popover is still there. But this time if I immediately click somewhere as soon as possible when the screen comes back on from suspend, I AM taken to a lock screen.
In other words, when suspending with a popover open, whether or not you get the lock screen seems to be dependent on how fast you click something on resume.
I hope I am explaining this well enough. This is the same behaviour on both my laptops.
