I’ve had a look at what was recently updated, found initscripts
as something that matches a recursive grep for utmp in /etc, and
sure, the diff between 2.93-8 and 2.95-1 in etc/init.d/bootmisc.sh
contains this:
- chmod 664 /var/run/utmp
+ chmod 644 "${utmp}" || log_warning_msg "failed to chmod
${utmp}"
So there we are.
Dmitry: please also move the chmod BELOW the chown, as chown
is known to sometimes reset permissions (in some documented
cases, not a bug):

XTaran: after “sudo chmod 664 /var/run/utmp” GNU screen works as
intended again, closing your bug.
glibc maintainers: unsure why screen works but not the example
code given that screen isn’t sgid… maybe you should have a look
at that, it still doesn’t work with the correct utmp permissions.
