Bug description:
After I upgraded to Ubuntu 25.10, I noticed that I'm periodically running out
of memory couple of times per day. `watch free -h` indeed shows a huge shared
memory usage (3 GB and rising). The shared memory usage climbs up at a rate
about 3mb/s and there's apparently no ceiling - something just uses all of the
memory.
`htop` shows no app with a huge usage of the shared memory, but I do notice
gnome-shell using a lot of virtual memory (5G and climbing up).
When I log out and log back in, the shared memory usage is reset to
100mb and starts climbing up again. `df -h|grep tmpfs` shows a stable
usage of 2mb, so this can't be the culprit. This leads me to believe
that `gnome-shell` is the culprit here. I'll try to disable all addons
and I'll try again.
