Creo que esto está relacionado, por ttyfast
lo que la pantalla no se vuelve a dibujar por completo. Intenta configurarlo en:
'ttyfast' 'tf' boolean (default off, on when 'term' is xterm, hpterm,
sun-cmd, screen, rxvt, dtterm or
iris-ansi; also on when running Vim in
a DOS console)
global
{not in Vi}
Indicates a fast terminal connection. More characters will be sent to
the screen for redrawing, instead of using insert/delete line
commands. Improves smoothness of redrawing when there are multiple
windows and the terminal does not support a scrolling region.
Also enables the extra writing of characters at the end of each screen
line for lines that wrap. This helps when using copy/paste with the
mouse in an xterm and other terminals.
