i think it's supposed to shutdown when tdm starts.
that's the actual bug.
https://bugs.trinitydesktop.org/show_bug.cgi?id=2806

i think the CPU usage is an after effect
If you notice, you can't access the tty's either....

you can stop it in a normal session with this command
sudo plymouth --quit

you can also, deactivate the splash option in grub

edit /etc/default/grub
change this line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT=""
save
and run
sudo update-grub
