Comment 14 for bug 1600622

I just discovered this the hard way. I happened to have speedtest.net opened in an unfocused Chromium tab on an inactive workspace and spent quite a bit of time going through a wild goose chase trying to figure out why my previously reliable DPMS/screen-locking setup suddenly flat-out refused to work at all. This was just running in the i3 window manager; no Gnome or KDE, nothing fancy. Closing the tab involved, or Chromium altogether, makes it work again.

The closest upstream bug I could find is https://bugs.chromium.org/p/chromium/issues/detail?id=654659 , but it appears to have been basically ignored by the developers.

It seems that Chromium has issues with inhibiting power management too aggressively. So aggressively I'd almost call it abusive.
