swaylock unlocks before password is typed fully when second monitor comes on after sleep

[japhir]

Likely related to #99. Quite often upon waking from sleep, it shows the unlock circle when I start typing but when my second monitor turns on the laptop is unlocked without me entering any password.

I'm using the latest sway version from the AUR sway version 1.5.1 and swaylock swaylock version 1.5-1-g5da2b1d (Jan 23 2020, branch 'master')

I can confirm this behavior and I actually see a crash:

Neither my circus nor monkeys, but it looks like #219 solved this? :)

You're probably right! I haven't seen this issue occur in a very long time. 🥳
