SMPlayer automatically starts (un-pauses) playback just after after resume from hibernation.
How to reproduce:
Open media in SMPlayer, e.g. a movie.
Pause it.
Hibernate PC
Resume from hibernation
What happens:
All SMPlayer instances start to play the media.
What is expected:
All SMPlayer instances keep the pause state if they were paused during hibernation.
NOTE: The bug exists for several years, I found it to be described here:
I have the same issue with up to date SMPlayer now on Kubuntu with usual hibernation.
