Bug ID: 465397
Summary: Pretty big memory leak in X11 only
Classification: Plasma
Product: plasmashell
Version: 5.26.90
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: xna...@hydra-development.net
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
SUMMARY
Since the last couple of days, 5.27 branch produces a pretty hefty memory leak
for me in the X11 session (Wayland is unaffected by this). The symptom is an
ever increasing memory consumption for the plasmashell process, as well as
increasing lag on the desktop: Drawing a selection rectangle on the desktop
starts to become choppy, as well as opening a context menu and hovering over
its entries.
I'm not sure exactly which commit caused it, and I don't know when exactly it
began since I've mainly been testing the Wayland session, but I'd say it
started at least 4 days ago (but well after beta testing for 5.27 began).
My plasmashell consists of the following:
Desktop:
- digital clock
- system monitor: network (line chart)
- system monitor: CPU (1 line chart per thread, 32 charts total)
Panel (top):
- standard kickoff
- weather
- CPU usage (%)
- GPU usage (%)
- RAM usage (GB)
- download (text)
- upload (Text)
- crypto currency price x2 (non-builtin plasmoid)
- window title
- global menu
- system tray
- digital clock
- peek at desktop
I can provide my plasma-org.kde.plasma.desktop-appletsrc if you think it helps,
but there are a lot of access / session tokens I'd need to purge first.
STEPS TO REPRODUCE
1. Log in to an X11 session
2. Open your resource monitor of choice and observe the plasmashell process
3. Wait ~10 minutes
OBSERVED RESULT
plasmashell's memory usage slowly creeps up, desktop becomes stuttery (after
~10 minutes, memory usage is already at ~1 GB for me)
EXPECTED RESULT
plasmashell's memory usage remains constant, desktop remains smooth
