Running an strace (sudo strace -u user /var/lib/snapd/snap/bin/chromium) shows the snap checks permissions on /tmp but then fails to make a directory /tmp/sh-thd.dmraw1.

Permissions on /tmp seem normal (set to 1777), we have plenty of space and inodes.
drwxrwxrwt 450 root root 9680 Feb 19 15:07 /tmp

I suspect something's happening with the way chromium child processes are unable to share files in /tmp, which would be a normal thing for snap isolation. Anyone seen anything like this before?
