I think Martin on to something concerning GRUB/Linux boot options, more specifically the "splash" one. With testing-updates enabled what currently happens for me:
If I set automatic login on I'm stuck with the standard infinite login loop, but with the distinction that I can now no longer enter another TTY via ctrl+alt+F3 for example to fix it straight away. The whole system now just freezes, so I fixed it via recovery mode.
Out of curiosity I then went and disabled the following line in /etc/default/grub and ran "sudo update-grub":
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Result: Automatic login now works perfectly, no issues anymore.
