I'm assuming there's something wrong with my machine, but the cursor seems blink out of place rapidly with any new character input until no suggestions are found. I'm using oh-my-zsh on WSL 2. I've tried using just zsh-autocomplete without any other plugins, and have tried other themes, but still getting the same bug. This doesn't happen on my other machine, so I'm not sure what the problem could be.

Same issue here with the Windows Terminal in WSL (Ubuntu 20.04.6 LTS).

I believe this happens with linux terminals as well, but not to the same degree.

Having the same issue with Ubuntu 24.04 and zsh 5.9 through Windows Terminal. It's purely cosmetic but extremely distracting.

I switched from Windows Terminal to WezTerm and the issue is gone. Overall the visual experience is a lot smoother actually. The root of this issue seems to be with hos Windows Terminal (and possible other terminal emulators) handle redrawing, because the visual experience is also hugely improved in other terminals applications like Neovim.
