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?
If you use the default (threaded) render loop and hardware rendering, does it make a difference?
There are three modes in hardware rendering : automatic, open GL and software. There are three modes in loop rendering : automatic, basic and thread. The thread loop rendering causes a crash to my system. I cannot use it. With the default mode (both automatic), there is a memory leak.
What crash? Have you filed a bug report for that?
When I use the thread loop rendering, about 10 seconds after the log in, my system entirely freezes. Even Ctrl+alt+Supp is not responding. I must reset to restart. I have not filed a bug report since I never use the thread mode.

Can you still reproduce the bug on the latest version?
(In reply to Fushan Wen from comment #6) > Can you still reproduce the bug on the latest version? No it appears that my issue has gone away. I can't say definitively which version fixed it but it is no longer a problem/
Thanks for the information
