I'm really not sure where the issue is, I spent a while trying to come up with something more useful to open an issue about, but I couldn't track down anything really useful.

When using sixel preview rendering it fails to display when running in wezterm directly, or when running in tmux within both wezterm and foot. In wezterm, with or without tmux, it mostly seems to render previous lines leftover from scrolling where the image should be. In tmux+foot it mostly seems to be blank, but e.g. when scrolling messages there's a single frame flicker of the image.

It does seem to work correctly when running directly in foot.

I also use sixel rendering in vifm which generally works in all the above situations, and running the ratatui-image example seems to work too. Just in case it was related to the StatefulProtocol which it says is more reliable I ported iamb over to use that, it didn't seem to make any difference.
