[Bug]: Ghost/Double characters appear during Zsh Tab completion (Redraw issue)

[amchii]

Current Behavior

I am experiencing a visual glitch where characters are duplicated (ghost characters) when using Tab completion in Zsh. For example, when I type do and press Tab, the terminal renders dd (double 'd') at the prompt line, even though the underlying command is correct.
