/bin/less started blinking instead of highlighting

So a few days ago after upgrading, /bin/less started displaying blinking text instead of highlight, which is not nice to look at. Setting environment variable

LESS="--use-color"

removes this blinking.

Did this happen to anyone else?

Can you be more specific? "Highlight" is not an ansi graphics mode attribute. Do you mean bold? And is --use-color the only flag passed to less? Wouldn't -R (or -r) need to be included for any ansi escape codes to be interpreted?

By "highlight" I mean change of background colour (and maybe swap foreground/background colours). This is not about formatting already in the input, but AFAIR /bin/less did "highlighting" to a number of things including to the bottom line message (e.g. "(END)"), and to text that matches a search. It started blinking these things instead, and --use-color is the first option I tried that changed that behavior. I have tried with and without passing -R .

This is in bash in urxvt . I am aware of variable LESS and aliases to set options, but not aware of any other way that options are being passed to less non-explicitly.

Thanks, that clarifies the symptoms well. The problem is then most likely with your terminfo settings. What's the output of `echo $TERM`?

Are you using any remote connection like ssh, or is this all on a single local machine?

Do you use the repo version of urxvt?
It doesn't seem to have set --enable-text-blink?

printenv | grep -i less
