If you want to disable syntax highlighting in Neovim 0.11+, you’ll need to disable lsp-semantic_tokens (lua vim.lsp-semantic_tokens.Stop(0, 1)), in addition to treesitter (TSBufDisable highlight; if you rely on Treesitter, it should disable stock syntax, syntax off). Better off using the quiet colorscheme as I do for quite a few months now. #vim
