[SOLVED] plasmashell memory usage grows rapidly and consumes all RAM

Link to an upstream bug report I created: https://bugs.kde.org/show_bug.cgi?id=466589

I am posting also here as I am not having this issue on Neon or Nobara so this might be arch specific.

Since very recently (not sure when exactly though) I have observed that the plasmashell process is consuming more and more memory at a frightening pace (e.g. usage grows to 22GB in the space of 3 minutes). Killing it doesn't always help (see video below).

video of plasmashell memory usage growing to 22GB in the space of less than 3 minutes.

https://mega.nz/file/o8pBARSY#QxC_k6BYt … uf3iMSFdMg

valgrind trace:

https://mega.nz/file/J0AhFIwK#pI_pFGmN8 … FPuwq3o1eo

I also tried:
1) monitoring the process with memleax but nothing was reported despite growing memory usage;
2) downgrading to glibc 2.36 but that didn't seem to help
3) disabling  libcamera in wireplumber
4) replacing wireplumber with pipewire-media-session

at the moment, as I type this, the process sits at 5.7 GB memory. Is there any way of checking where this memory gets allocated?

Thanks for any pointers

Re: [SOLVED] plasmashell memory usage grows rapidly and consumes all RAM

memory seems to increase with each entry in the journal, but I am not sure if kpipewire is the offending component
