ncurses/curses not redrawing

[mmskv]

Hi,

Ncurses interfaces don't redraw on some programs after i resize them. So i have pinned down termite to be the cause of it, as rxvt-unicode draws ncurses fine.

Ncurses programs that appear to work: vim, nano, tmux, mutt?, alsamixer, top?.
Ncurses programs that don't work: mocp, ranger (although it uses python curses module), menuconfig, htop.

Termite works fine with ncurses on ArchLinux, but on fresh Gentoo install I can't make it work.

What did not help:
Recompiled sys-libs/ncurses with unicode, threads, gpm, cxx, tinfo support
Recompiled termite from this repository, tried two portage overlays - gig and gentoo-zh, compiled vte-ng from gentoo-zh, which did not work. Then compiled vte with termite patch and termite itself, from gig overlay. It did not work too.

Here is the example of mocp not redrawing (<c-r> did not work too).

and this is if I shrink window:

same problem with ranger (:refresh did not do anything):

works fine with urxvt:

This is how menuconfig looks when shrinked:

Perhaps this issue is related to #665 or #88, but i did not experience wrong scale during startup, only after resizes.

Information about installed packages:
termite v13 (Upstream version did not work too)
vte - 0.48.4:2.91 (vte-ng did not work too)

Fix: fish-shell/fish-shell#7707

Adding these lines to config.fish fixed the issue for me.
