Plasmashell memory leak

[SpecialEd]

<<<<<<

Yes I am. When I browsed the issue I read that indeed that could be the cause of the memory leak but I do not think that it is in my particular situation. I have slideshow as screensaver set for about a week now and I never had any significant memory leak issues.<<<<<

I'm not saying Slideshow is your problem but seemingly unrelated updates can affect the way Slideshow and programs like Discover, etc., behave. Ask me how I know.

You could also look at what's causing your CPU usage to be 57%.

Oh that was the infamous update-apt-xapi.

Are you using "Slideshow" as your screensaver?

Yes I am. When I browsed the issue I read that indeed that could be the cause of the memory leak but I do not think that it is in my particular situation. I have slideshow as screensaver set for about a week now and I never had any significant memory leak issues.

It's usual that plasmashell keeps increasing size during a session but nothing significant, I do not recall seeing it above 300 MB (usually my system starts with it around 180 MB).
Yesterday I remember doing stuff like adding themes and widgets to Plasma, changing themes (but I kept no new widgets besides the ones I already was using), testing different panel layouts, using Wine programs to look for duplicate files, I remember also using Firefox for normal browsing and watching a video stream, also used Kodi for a bit. Maybe I did some more stuff but this is what I can remember.

Recalling my actions and the abnormal plasmashell size I'm tempted to jump to the conclusion that the cause could be the customization I was fooling around with, all the other actions I have done before without similar plasmashell behave.

[chimak111]

Can you disable redshift-gtk and see if that helps?

You could also look at what's causing your CPU usage to be 57%.

Including the output of

inxi -Fxz

may be informative as well. If you don't have inxi installed, get it with sudo apt install inxi.

See https://www.kubuntuforums.net/showth...ll-Memory-leak for widgets that could be misbehaving.

Mine is bigger than yours!

I've got a memory leak in plasmashell, it has at this moment more than 1 GB:

How can I identify the root of the leak?
