light-locker: strange beheavior when trying to unlock the screen/open the lid

Question

loki has light-locker
I have setup that when I close the lid of the notebook the screen locks (not suspends)
when I close it and then after a while open it, I have to wait a few seconds to get rid of the annoying message saying

"you'll be redirected to the unlock dialog automatically in a few seconds"



After it I get the normal lock screen where I can write the password down.
The sad thing is that after y pŕessed enter to submit the password I get the same black window message for a couple of seconds

Is there a way to disable this annoying black window to go straight to the lock screen?

I've only found this
