Describe the bug

After one of last update on cocnvim on github with semantinc highligh enabled
if I scroll by using arrow keys it annoyingly flickers. I attach also a video where
in the first part I use arrow keys to scroll (when it flickers) and in the second part
I scroll by using the mouse wheel (and it does not flickers)

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't
reproduce it

set nocompatible
set runtimepath^=/Users/demichel/.vim/plugged/coc.nvim/
" Use <c-space> to trigger completion
syntax on
set nohidden

  • Start (neo)vim with command: vim -u mini.vim

  • open the following file:
    sim.hpp.zip

  • type G then CTRL-O to go back to first line

  • start scrolling down by pressing once "page down" and then repeatedly pressing "down arrow"

  • it flickers

Screenshots (optional)
