What is the default setting that makes Vim really slow on a Mac screen?

The problem is not resolved, although I accepted one answer.

Problem: Vim updates the screen to Screen on Mac very slowly, although lazyredraw and showcmd are disabled .

Line numbers fall on foldColumn as shown below, for example, when I have line numbers alt text http://dl.getdropbox.com/u/175564/vimScreenFold.png

When I have nothing in my .vimrc, the problem can be seen by multiplying the comment lines by each other: alt text http://dl.getdropbox.com/u/175564/vimScatteredBug.png

I did not type the following comment more than once on the left side

"set list...

Observations

  • seemed to be found only in comment lines and empty lines . However, I have obtained evidence (2) that shows that this is not so.
  • scattering occurs mainly in the left window. They are also found with one window. However, this is more difficult to detect.
  • The error occurs a little differently when I have nothing in .vimrc. However, "stagnation" occurs in both situations: with an empty .vimrc and with a non-empty .vimrc.

Error identification

Dependent Variables

  • Vim is automatically added depending on the comments . I noticed fading pixels when Vim automatically put Python # comment marks in my files when it could not display the whole file.
  • Depends on at least OS / X Leopard.
