nom sometimes breaks line wrapping in tmux

Hey, so I will try to explain the exact issue but I don't really know how to nail this down any further. My use case is pretty much a shell script like this:

nix-store nix-store --realise --log-format internal-json -v … 2> >(nom --json)
result/bin/switch-to-configuration

I usually run this in tmux, but sometimes that breaks line wrapping. What happens is that rather than the newline creating a new line, the cursor stays at the rightmost column and just prints all characters in that position. This is especially noticable with long lines of services being started/stopped. The issue also persists when the commands are done and I get thrown back into my shell.

An issue is that this doesn't always happen, only some times. I assume it's related to what is being outputted (like long build names and whatnot) so it doesn't always trigger.

One thing of note is that I usually use ttyctl -f in zsh, which means that my stty settings should be reset once a command is done (and the prompt is being drawn). This is why I assume it's not stty-related and rather something else.

I use tmux 3.3a, zsh 5.9 and nom 2.1.1.

Please tell me if there's anything to narrow that issue down.
