Thanks for looking into.
But tmux 2.4 in 8.0 base and pkgsrc tmux 2.6 exhibit the same behavior
on my 8.0 system...
This was not the case of base tmux 2.4 in 7.1.1. I noticed the change in
behavior
almost immediately after upgrading with the base tmux. I've tried building
pkgsrc tmux 2.6 with system curses and ncurses; I've tried importing 7.1
screen.terminfo as well before having any info.
Regards,
Courtney
