Actually, the MacVim bug is not solved. I just confirmed with Raimondi from IRC
that it is an actual bug. Here are the details:
The bug seems to be with the `redraw` function in files that don't fit in one
screen. To reproduce, open a "long" file (as in, one with enough lines so that
it doesn't fit on one screen) with the following command:
mvim -N -u NONE -U NONE file
Then source the vim-bling plugin (because this plugin will force the bug to
appear):
:so vim-bling/plugin/bling.vim
The plugin can be found here: https://github.com/ivyl/vim-bling
Alternatively, put the following code in a file (say blink.vim), and source it:
highlight WhiteOnRed guibg=red
function! HLNext (blinktime)
let [bufnum, lnum, col, off] = getpos('.')
let matchlen = strlen(matchstr(strpart(getline('.'),col-1),@/))
let target_pat = '\c\%#'.@/
let ring = matchadd('WhiteOnRed', target_pat, 101)
redraw
exec 'sleep ' . float2nr(a:blinktime * 1000) . 'm'
call matchdelete(ring)
redraw
endfunction
nnoremap <silent> n n:call HLNext(0.4)<cr>
nnoremap <silent> N N:call HLNext(0.4)<cr>
This code also forces the error to appear.
Then search for a word (or even a character) and press `n` or `N`.
Normally, you will see the caret jump at the end of the line before going back
to the next search result.
Note that I installed MacVim with Homebrew on OS X 10.8.5, but I built the code
from master/HEAD with the following command:
brew install macvim --HEAD
Here is the output of `mvim --version`:

Also, the bug does NOT appear in terminal Vim (even the one that comes with
MacVim).
