Please give a specific example of the key you press? You will get
different results if you press a modifier key like Shift (screen wakes
up but password prompt does not appear), or a key that could be part of
your password like "a" (password prompt appears and that letter is typed
into the password box).

What exactly do you mean by "wipe"? Click the mouse button and drag
upwards? Click the mouse button and drag downwards? Touch a touchscreen
and drag in some direction?

Please look for more information about this crash in the systemd journal
or in /var/log/syslog, and send it to the bug report.

A backtrace from the crash is also likely to be useful. Since you are
using systemd, here is a convenient way to get backtraces:

- Install the systemd-coredump package
- Enable the debug archive
  https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols
  and install relevant debug symbols
- Reproduce the bug, causing the crash to happen
- Use "coredumpctl gdb" to debug the most recent core dump
- Use the "bt" command as in
  https://wiki.debian.org/HowToGetABacktrace#Running_gdb
