Image not cleared after switching tmux window

[Shihua Zeng]

After some exploration I found another issue that after switching tmux window the image in the previous window is not cleared.

Here is a short screen recording that demonstrate it:

Peek.2023-10-24.11-46.mp4

Environment:

• Terminal: kitty 0.29.2 + tmux 3.3a (with allow-passthrough on)
• Neovim: NVIM v0.10.0-dev-1334+gd2d38858d1
• image.nvim: 1cb60be1cdc108e3a3b09cb0ed115ef75ce51320
• OS: Linux 6.1.58-1-lts

Plugin config:

package.path = table.concat(
  {
    package.path,
    vim.fs.normalize('~/.luarocks/share/lua/5.1/?/init.lua'),
    vim.fs.normalize('~/.luarocks/share/lua/5.1/?.lua'),
  },
  ';'
)

require('image').setup({
  window_overlap_clear_enabled = true
})

Also the window_overlap_clear_enabled option does not seem to work:

For a convolutional operation, the stride 
**S** denotes the number of pixels by which the window moves after each operation.

Hey, you need to set tmux_show_only_in_active_window = true and also set -g visual-activity off in your Tmux config.
It's all a big hack, it will try to find the tty you switched to and write the clearing control sequence to it 👀

It works, thanks for quick response!

@3rd The window_overlap_clear_enabled still does not work, though:

After :call nvim_open_win(nvim_create_buf(0, 0), 0, { 'col':10, 'row':8, 'width':100, 'height':20, 'relative':'editor' }) (open a floating window that covers the image):

[Andrei Neculaesei]

It's because the buffer has no filetype and of the window_overlap_clear_ft_ignore = { "cmp_menu", "cmp_docs", "" } default.

Thanks, setting this option to empty table solves the problem.
