Ugly empty spaces between intented lines

Hi, I have set up my neovim config listchars like so:

vim.opt.listchars = { tab = "│ ", trail = "·", precedes = "<", extends = ">", nbsp = "○" }

But for empty lines between the indentations there are these awful holes left.

I used to use intent-blankline.nvim but I want to try to tone down my plugin usage, and I pretty much used it only to fix this issue, could somebody help me?
