Public bug reported:
I let my 1-year-old child play with the login screen for ~5 minutes.
After hitting all kinds of keys (the sequence seemed to be very
complicated) we ended up with a black screen with mouse cursor only
slowly responding to mouse movement and lagging behind.
I couldn't do anything else but reset the PC.
First this seems to be funny, but then you realize how embarrassing it
is. It absolutely should not be possible to crash the login screen just
like that. How is that even possible? The login screen should just
either accept a password or reject it no matter what keys are being
pressed.
