Setting the background option eventually messes up the Normal highlight.

This is the everforest theme with background=dark.

If I set background=light then I get this:

Both of these are correct.

Now, if I set background=dark, I get this:

And set background=light gives me this:

If we go back to the dark version, you can see that the background is black (or something close to it). However, running the following command yields the "expected" background color:

:echo synIDattr(synIDtrans(hlID("Normal")), "bg")
#2d353b

If the window is resized at all then it fixes the colors. We can also fix them with this function:

local function fix_colors()
  local bg = vim.fn.synIDattr(vim.fn.synIDtrans(vim.fn.hlID('Normal')), 'bg')
  local fg = vim.fn.synIDattr(vim.fn.synIDtrans(vim.fn.hlID('Normal')), 'fg')
  vim.cmd('highlight Normal guibg=' .. bg .. ' guifg=' .. fg)
end

Have same problem, I use f-person/auto-dark-mode.nvim and it breaks the colors in dark mode

Accidentally ran into a workaround, if you press Cmd-+ (in other words cmd + shift + =) it increases the font size and fixes the colors. Then you can change the font size back with Cmd-_ (in other words cmd + shit + -).
