Hello this is the first time I had trouble after an update, but it’s a big one as it left my system completely inoperable.
I am using KDE Wayland and after installing the update and rebooting my memory (32 GB) is completely filled to the point where I couldn’t start any new programs. The problem persisted across several reboots and switching to a X11 session.
I could luckily still start Yakuake and found the culprit to be plasmashell which was sitting at 28GB memory usage.
Only thing I could do was to revert the update via Timeshift.
EDIT:
Via binary search I found the package responsible for the issue.
Surprisingly it’s glibc (and/or lib32-glibc) going from 2.36-7 → 2.37-2
For my machine this is reproducible and leads to the issue mentioned above.
