Hi,
ncurses-6.6-20260131 and ncurses-6.6-20260207 are breaking tmux. Once I

Downgrading ncurses to 6.6-20260124 or older "fixes" the issue.
The changes in 20260131 were all additions to existing terminal descriptions.
Nothing was removed.
The report doesn't say how ncurses was built or installed.
(there's nothing that demonstrates a problem with ncurses or tmux)
It would be interesting to know whether Lars has the same problem with
other TERM settings or only with xterm-256color.
