cursorcolumn drastically slows down scrolling

[thunder-coding]

Problem

Open a large file with syntax highlighting. It does not need to be super large (I could also reproduce it with 30-40 , but syntax highlighting is a must to reproduce the issue). Scroll through the file using hjkl motions, there is significant lag when you keep spamming hjkl with 20 repeat/s desktop environment configuration. I tried capturing this with OBS, but with 30 fps, the problem isn't noticable in the recording, and at 60fps, OBS drops a lots of frames for me.

This issue seems to be similar to #8159

Steps to reproduce

nvim --clean
:e src/bit.c
:lua vim.opt.cursorcolumn = true

Expected behavior

NeoVim should not lag terribly

Neovim version (nvim -v)

0.9.5 (also reproducible on 0.6.0 and master (did not check all versions in between))

Vim (not Nvim) behaves the same?

yes, but it's not that visible in vim as it is in neovim. 9.1.0252
