  • This can sometimes results from drawing errors or misconfigured terms (or misconfigured colorschemes). Check $TERM (env var), t_Co (vim option set based on TERM), and try doing a :redraw Commented Oct 23, 2018 at 13:35
  • Thanks! Your comment lead me to checking if it was an issue with screen not supporting 256 colors, and so I added the line term "screen-256color" to my /etc/.screenvrc file, and that solved the problem! (however, it did create a new problem in that now if I add the line set termguicolors to my .vimrc file it just changes all text to white... which means I can't use themes that rely on the termgui option like ayu). But at least some custom themes work now! Commented Oct 24, 2018 at 5:52

    ill write the answer a bit later; as for the termguicolors, well, 256-color terms dont support truecolor (i think it’s 20-bit color? Much more than 256). If you really want termguicolors, you need a term that supports it (afaik tmux/screen do not), or use gvim. I happily live with 256 colors bc i do everything in tmux. Commented Oct 24, 2018 at 13:59

    Oh, okay, perfect. Well I'll live with 256 colors as well instead of truecolor. It looks like according this forum chain I found there is a way to get screen to support truecolor, but it's a pretty janky process to get there and I tried a little bit of what they said but it didn't immediately work and I don't want to dump a bunch of time into trying to support that. Thanks for helping me get 256 colors working! Commented Oct 24, 2018 at 18:13

    Looks like a problem with BCE. Does :let &t_ut='' fix it? See snk.tuxfamily.org/log/vim-256color-bce.html Commented Oct 24, 2018 at 19:31
