Bug ID: 414326
Summary: PlasmaShell 100% CPU
Product: plasmashell
Version: 5.16.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: antonio.mario.car...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
Ubuntu 19.10, installed with lowlatency kernel.
Run Kde from startx (start system in runlevel 3)
open Firefox.
I have a bookmark tab that have lots of folder and links, so just move the
mouse to navigate in the bookmarks menu in the bookmark tabs. Open a console
and
run htop, and see how plasmashell goes to from 60% to 100% and suck all cpu,
the same also for firefox that seems to be influenced by several delay in
rendering the menu.
I assume that there is a big problem maybe with the compositor or other issues
like that.
STEPS TO REPRODUCE
1. as above.
2.
3.
OBSERVED RESULT
Menu open with delays, PLEASE, just open X with a single xterm (no other
desktop environment) run metacity as window manager, and firefox, you notice
that the menu issue is solved, and there the cpu load of firefox is quite low.
EXPECTED RESULT
Usable desktop in linux.
