Do you get memory leaks with the default Breeze theme? I've had bug 471642 open since 5.27 for the same sort of leak, and as of 6.3 its still there, and probably worse. I've provided heapstacks for review of memory usage at the time, but nothing has come of it. You'll probably want to install heapstack as well at high memory and provide for the devs. Okay guys I THINK i have found the issue And I say I THINK because I have tried many things and Im not yet sure what the issue is and sometimes it has returned etc but I can now mantain it at least for now at around 600-900 MiB after 10 minutes time elapsed normal use by removing my Walpapers. I think it was specifically the Walpaper Presentation plugin, but as of writing this Im yet figuring out what happens and if that indeed is the problem or not. Kind of frustrated trying to fix this but thanks to the 2 replies. I'm gonna do some more reboots/relogins putting on/off that feature to check. Hopefully I have found the source of the issue. Otherwise, I really don't know what it is, I have even tried removing taskbars (In reply to Michael Butash from comment #2) > I've had bug 471642 open since 5.27 for the same sort of leak, and as of 6.3 > its still there, and probably worse.

I have installed it but i dont quite get how to use it the GUI confuses me as there is many things I don't get What I'd done was attached it using the pid of the plasmashell using "heaptrack --pid $pid", then when at high memory, kill -9 said pid and plasmashell should restart, and heaptrack should spit out a file and launch in analyze mode. > Walpaper Presentation plugin
Is that a 3rd-party wallpaper plugin you installed? Or a translation of the built-in "Slideshow" wallpaper that shows different images of your choosing?
(In reply to Nate Graham from comment #6) > > Walpaper Presentation plugin > > Is that a 3rd-party wallpaper plugin you installed? Or a translation of the > built-in "Slideshow" wallpaper that shows different images of your choosing? I have my system set to Spanish, but yes, this refers to the built-in slideshow feature. I’ve noticed that disabling the slideshow and switching back to a static wallpaper significantly slowed down the memory leak. Previously, plasmashell would reach around 20GB of RAM usage within just three minutes. After disabling the slideshow, it took about an hour to reach 9GB, indicating a much slower leak. Switching back to the default Breeze theme completely stopped the leak. I was able to leave my system running for 13 hours with plasmashell maintaining a stable usage of around 800 MiB. Now, I’ve reapplied my usual theme, (Shades of Purple)[https://store.kde.org/p/2090553], but only as a Global Theme to check if the issue persists. As of writing this, with the theme enabled, plasmashell is using 946 MiB after 13 minutes. The memory usage is slowly increasing again, suggesting that the leak might still be present. I’ve also collected logs with heaptrack and will share them later once I confirm whether the leak continues with this theme. Created attachment 179906 [details]

Alright, definitely this theme provokes a memory leak, I was back again at 1.0GiB usage after 26mins, I have changed back to Breeze Dark and it went back to 962MiB and Ill keep an eye to see if it stays stable for long, will update on this. For now, here are some heaptracks logs of different times. Sorry, I didn't named them accordingly for better organized tracking and some are from more memory usage than others etc. Also, I have some of 10MiB that I can't upload here Default Breeze theme is now leaking memory, too, but very slowly Yesterday it wasn't as I said i was able to run it for 13 hours at 800MiB For reference heaptrack instructions were at https://discuss.kde.org/t/high-memory-usage-from-plasmashell-is-it-a-memory-leak/29105/9 And this is being discussed in https://discuss.kde.org/t/plasmashell-using-40-gb-ram/32282/9 If there is a mem-leak in plasma with breeze, you can use the same heaptrack technique to diagnose it, it should probably be a new bug with an important priority, since breeze is the most commonly used theme. In your traces, I could identify a leak in libEGL and libEGL_nvidia... Both of which aren't maintained in plasma. |
