Bug ID: 381608
Summary: Plasmashell use 100% cpu
Product: plasmashell
Version: 5.10.2
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: quelque_...@yahoo.fr
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
For some reason, plasmashell uses more than 100% cpu, I don't why. I think it
is when I leave my computer stalling for more than 5min, but I don't need to
get to the screensaver to have that.
I'm using plasmashell 5.10.2, on archlinux, with the nouveau driver 1.0.15-1.
uname -a:
Linux coincoin.mooo.com 4.11.5-1-ARCH #1 SMP PREEMPT Wed Jun 14 16:19:27 CEST
2017 x86_64 GNU/Linux
Nothing's relevant in dmesg.
Here's the stack trace:
