No one can reproduce this?
I prepared a video instruction which can helps:
https://youtu.be/0ipQnMpZG1Y

1. Run script which would calculate watchers:
$ for i in {1..99999}; do sudo curl -s
https://raw.githubusercontent.com/fatso83/dotfiles/master/utils/scripts/inotify-consumers
| bash; done

2. Run the game "Devision 2"

3. Run 20 windows of Google Chrome with such script
$ for i in {1..20}; do google-chrome-unstable
--profile-directory="Test-2" --new-window --start-maximized
"youtube.com" &; done

I hope after it you see the desired backtrace.
