Invalid window ID on colorscheme change

[Davincible]

Description

I call colorscheme every x minutes, which now for some reason results in the error below. Used to work fine below.

I manually call colorscheme xx I also get it.

Error detected while processing ColorScheme Autocommands for "*":

Can be fixed by checking if the window is valid on view.lua:441

-- used on ColorScheme event
function M.reset_winhl()
  if M.get_winnr() and vim.api.nvim_win_is_valid(M.get_winnr()) then
    vim.wo[M.get_winnr()].winhl = M.View.winopts.winhl
  end
end

Great digging. Please create a PR.

I'm not sure if its specifically my setup, but I seem to get more of these kinds of errors;

Let's track that separately.

Please raise a new bug report, this time with an nvt-min.lua that we can reproduce the problem with. :colorscheme default isn't a great test case...
