Screenshot

I can see the window below, that doesn't happen on the rest of the terminal.

Dockerfile that reproduces the problem (if possible)

Sorry for the late reply.

Hmm, this seems to be a problem with Neovim and the window manager, not with fzf-preview.
Can you try to change the settings there?
