viu inside tmux seems to spam control codes into the pane title

[akda5id]

Using ghosty, and the tmux config from these dotfiles, whenever I run viu from inside tmux, it seems to hang. When I turn on pane titles, I noticed that there are control codes in the pane title, and confirmed that they appear/change when running viu. So, there is something goofy going on. I thought it might be worth asking here, as I know Omer uses ghosty, tmux and viu.

I have tried changing $TERM to screen-256color, and then viu works, but in blocky rendering, of course.

Anyone have some thoughts?

Edit: I have solved it by switching to timg, which works fine in tmux.
