Comment (by jmroot):

 I'm not sure which features tclock is using, but your initial screenshots
 are clearly demonstrating that iTerm lacks repeat character support, as
 mentioned in the ncurses FAQ. Older versions of terminfo mistakenly do not
 list xterm as supporting that feature, which is why iTerm works when using
 the older version. You don't list any iTerm results with TERM=iterm – if
 that works correctly, then it's definitely a matter of expected vs actual
 terminal capabilities.

 Note also that Debian stable ships a version of ncurses from 2016 and
 still uses ABI 5.

 It's of course possible that there are bugs, but if so they are likely to
 be from upstream since the MacPorts packaging makes very few
 modifications.
