Steps to reproduce this bug using minimal vimrc

Open a long complex file (e.g. Line length 260 .tsx file)

Actual behaviour

Takes about 1~2 seconds to load the page

Expected behaviour

Take less than 1 seconds to open the file (my previous theme kristijanhusak/vim-hybrid-material used to take less than 1sec)
