One of your path styles seems to be set to use strikethrough. What's the output of typeset -p ZSH_HIGHLIGHT_STYLES?

I think underline is somehow being replaced by strikethrough. This is happening only in KDE Konsole, and not in other terminal emulators I've tested (terminator, gnome-terminal, alacritty, kitty, xterm).

Any idea what could be causing this issue in Konsole?

[danielshahaf]

Is $TERM set to the correct value?

Can you reproduce the issue when a program other than zsh tries to use underline? For instance, look at the underlines in the third paragraph of man zshzle | less.

Seeing the same issue in man pages, when viewed from Konsole. It appears properly underlined when opened in other terminal emulators. $TERM = xterm-256color

It appears to be related to the Font size. Strikethrough appears when the font size is < 26.

Font size = 10.50

Font size = 26.0

So it's not a zsh-syntax-highlighting issue. Closing.

It appears to be related to the Font size. Strikethrough appears when the font size is < 26.

Thanks for the extra details.
