visible at 0:32 and 3:56.

dit 0.5 Pantheon Terminal NixOS 18.03.132275.2352d46904d (Impala)

Again, not reproducible with GNOME Terminal.

Here i have a (private) file where dit don't show every line. Similar behavior in both Terminals.

I've had htop users in the past who had similar weird problems when their libncurses version did not match the version of their ncurses headers. Do you happen to have multiple ncurses versions installed? There may be conflicts with the OS-provided one.

i think that shouldn't happen, but i ask...

could it be a problem that we use ncurses 6.0-20171125? maybe we need a fix like this? https://github.com/NixOS/nixpkgs/commit/8afcfb2bb6681c56ecf21e056d91d6748d953997

That's probably not it: I run ncurses 6.0 here.
