Snapshot 1.0.300.5 defeats dpms screen blanker
I have snapshot 1.0.300.5 running on openSUSE Tumbleweed and my preferred screen blanker, xset +dpms xset dpms 300 400 500 xset s on is defeated whenever a vivaldi-snapshot instance is present. Closing vivaldi allows the screen to blank as expected. I don't know if that is the case with vivaldi-preview-220.127.116.11 but I will check and advise.
And today, neither blocks dpms. ??
