https://bugs.freedesktop.org/show_bug.cgi?id=103897 --- Comment #6 from Andrew Randrianasulu --- Bug still here on 4.14.9-x64. But it seems if I use "xset dpms force standby" X also doesn't eat CPU anymore. If X enters such state by default after some time of user inactivity - it also don't eat CPU time. Unfortunately, I can't do anything useful wih seamonkey if my screen is off. -- You are receiving this mail because: You are the assignee for the bug.
