[BUG] my fzf search results display irregularities in iTerm2

[littlecorgi]

Describe the bug

When I input any command and then press the tab key, several additional lines are displayed.

I can make sure:

• I am using the latest version of fzf-tab
• this is the minimal zshrc which can reproduce this bug
• fzf-tab is loaded after compinit
• fzf-tab is loaded after plugins which will wrap Tab, like junegunn/fzf/completion.zsh
• fzf-tab is loaded before zsh-autosuggestions, zsh-syntax-highlighting and fast-syntax-highlighting.

Environment:

• OS: macOS 13.3
• zsh version: 5.9 (x86_64-apple-darwin22.0)
• zinit version: v3.10.0 (darwin22.0_x86_64)

Minimal zshrc

# 应用bash文件里面的配置
source ~/.bash_profile
# 应用spaceship的配置
source ~/.spaceship-prompt
# 应用zinit
source "$HOME/.local/share/zinit/zinit.git/zinit.zsh"
autoload -Uz _zinit
(( ${+_comps} )) && _comps[zinit]=_zinit

Finally, I resolved this bug. The issue was caused by a setting in iTerm2 that I had enabled.
iTerm2 -> Settings... -> Profiles -> Text -> Unicode -> Ambiguous characters are double-width.

After disabling this setting, the display returned to normal.
