OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Image Wallpaper
Assignee: notm...@gmail.com
Reporter: tempori...@sfr.fr

Target Milestone: 1.0
SUMMARY
Description of problem:
- Memory leak of the plasmashell process when using a slideshow
Version-Release number of selected component :
- KDE Plasma 5.20.4
- One desktop, 4 activities including a slideshow
- KDE Frameworks 5.76.0
- Qt 5.15.2
- Kernel 5.10.56-desktop-1.mga8
- OS 64-bit
- 16 Go RAM
STEPS TO REPRODUCE
1. create a folder containing two big pictures
2. create 4 activities with a slideshow (time 15s) pointing to the picture
folder
3. log out then log in
4. visit all activities one time to start the leak
5. survey the memory consumption with the plasmoid
OBSERVED RESULT
Plasmashell's memory occupation increases continuously and finally crash
EXPECTED RESULT
Memory consumption must be stable
SOFTWARE/OS VERSIONS
- Linux Mageia8
- KDE Plasma 5.20.4
- One desktop, 4 activities including a slideshow
- KDE Frameworks 5.76.0
- Qt 5.15.2
- Kernel 5.10.56-desktop-1-1.mga8
- OS 64-bit
- 16 Go RAM
ADDITIONAL INFORMATION
Workarounds
- Selecting a static background image as a replacement for the slideshow fixes
the problem
- I have launched kcmshell5 qtquicksettings
set Render loop to "Basic"
and Rendering backend to "Software".
I noticed a degradation of the Plasma rendering : I can no longer see the text
below my desktop icons, only the picture, but it stopped the leak.
I can no longer reproduce the leak problem. Everything looks stable.
What is the explanation ?
Which software is the culprit ?
Which software updates should I inform the Mageia KDE maintainers to fix the
issue?
