A couple of leaks were discovered that snuck into 3.30.1.
One of the leak can be quite severe, but both fixes are trivial and should be safe, thus marking as a proposed blocker for F29.
With blocker, I mean freeze exception.
mutter-3.30.1-3.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-947cd0b815

I'm still experiencing this problem on mutter-3.30.2-2.fc29. Gnome-shell went from 400 MiB to 1 GiB in five-or-so hours. Gnome-shell version: 3.30.2-1.fc29.
