On my system plymouth had been installed without me noticing.

At some point I realised that the first virtual console became unusable:
not all keys I was pressing did work in shells and programs, whereas the
other virtual consoles did continue to work properly.

Further investigation (with lsof) showed that plymouth was reading /dev/tty1
concurrently with the running shell / programs. So it got some of the
keypresses and that was why I had to type e.g. letters several times.

For arrow keys, the escape sequences were even split, plymouth read
parts of them while the other parts were read by the shell or currently
running program, leading to very odd behaviours.

Uninstalling plymouth solved the problem.

Plymouth should exit once the boot is finished so that shouldn't happen.

There is a bug (whether it's a bug is debated) in systemd version 245-1 where plymouth can be restarted.

Can you please check if you have 245-1 installed or do you have an other version?
