how to disable URXVT's auto-formatting of URLs? [SOLVED]

[ExecutorElassus]

I'm trying to use yt-dlp (a newer fork of youtube-dl), but when I type or paste a URL in at the end of the command, my urxvt terminal auto-formats it with an underline, and then yt-dlp doesn't recognize it as a URL.

I've already checked that it's not expanding the "?" character (see here), but that's not it.

Any advice?

Cheers,

Just in idea, are you using url-select perl extension ?
In my ~/.Xresources, I used to have this enabled:

I've commented out all of those lines, with no effect.
