journald writes to all consoles simultaneously

[df8oe]

During debugging network/kernel issue I stumbled into scattered screen because journald is writing to all consoles simultaneously. This was not identified before because of I accessed the rpi via ssh. There the issue does not exist. But when I attach a local monitor is does not matter what console I am using - journald writes its output to all of them simultaneously. Where can I stop this (and write to tty7 e.g.)?
