This is a mawww/kakoune#4801 copy-paste. I noticed I actually use this plugin and was diverted here. Thanks :)

I wonder if this is not due to the use of the -ro flag, which prevents kak-ansi from removing the escape sequences. Could you try without? If that works a possible solution would be to only set the read-only flag once all data has been received from stdin (and the escape sequences processed).

[razcore-rad]

Yea, I already tried without the -ro flag. That's not it.
