Vim very annoying and slow behavior with ConEmu

3

1

This GIF image illustrates my problem:

My execution environment:

  • Windows 7 SP1
  • Vim74 (Windows version)
  • ConEmu latest version x64 version

My .vimrc file: 529-line file on codepad

Settings related to my problem (as I think):

  • set term=xterm
  • set t_Co=256
  • let &t_AB="\e[48;5;%dm"
  • let &t_AF="\e[38;5;%dm"

My problem:

  1. When I scroll down, texts are rendered very slowly.
  2. Annoying cursor(?) appears randomly on screen.
  3. I have this problem even with plain text files.
  4. Very short (less than 50 lines but with scrollable line long) files.

Solutions I tried:

  • Reduce synmaxcolum by set synmaxolum=50
  • Remove line set=xterm (this solves the problem but I need 256 colors)
  • I tested on Ubuntu and Cygwin with same .vimrc file and plugins but there was no problem at all :-0
  • GVim works fine

Your gif doesn't show full window. – Maximus – 2015-07-10T09:43:03.313

Which vim are you using? It is possible to run vim inside Conemu in multiple ways: embed graphical VIM window, launch cmd and run text mode vim, or run vim inside MinGW or other unix like environment. Judging from term variable, it doesn't look like graphical VIM. – Abel Cheung – 2015-07-10T12:47:13.883

@이햇살 Using gvim fixes it. – Simon Hartcher – 2017-03-28T10:31:00.623

  1. xterm gives you 8 colors, not 256. You need xterm-256color for that.
  2. If your $TERM is xterm-256color (or some similar value) you don't need to lie to Vim with set t_Co=256.
