Strange smearing behavior over external windows (lazygit.nvim)

[nadiamoe]

Hi there, thanks for the great work on this plugin, I'm really liking it!

I've found however an issue on how it interacts with https://github.com/kdheepak/lazygit.nvim, which brings lazygit inside neovim and I use extensively.

While editing text inside this window, the animation seems glitchy, covering characters while it feels like it shouldn't:

output.mp4

This is my config:

{
    "sphamba/smear-cursor.nvim",

    opts = {
      -- Smear cursor when switching buffers or windows.
      smear_between_buffers = true,

      -- Smear cursor when moving within line or to neighbor lines.
      -- Use `min_horizontal_distance_smear` and `min_vertical_distance_smear` for finer control
      smear_between_neighbor_lines = true,

      -- Draw the smear in buffer space instead of screen space when scrolling
      scroll_buffer_space = true,

      -- Set to `true` if your font supports legacy computing symbols (block unicode symbols).
      -- Smears will blend better on all backgrounds.
      legacy_computing_symbols_support = false,

      -- Smear cursor in insert mode.
      -- See also `vertical_bar_cursor_insert_mode` and `distance_stop_animating_vertical_bar`.
      smear_insert_mode = true,

      min_horizontal_distance_smear = 4,

      filetypes_disabled = {
        "lazygit", -- Behaves weirdly
      },
    },
  },

I've tried to disable the lazygit buftype, but that doesn't seem to help either.
