[xvim64]

environment

• vim: gvim v9.0.1585
• vim-airline: 423fe9e
• OS: Windows 11 x64 22H2
• Have you reproduced with a minimal vimrc: no ( "It occurs in "vim-plug + airline + airlien theme + coc + coc-rust + coc-sumneko-lua".)
• What is your airline configuration: default
  if you are using terminal: no

The lua Emoji appears in an inappropriate place in the C++ status bar.

I have no idea what you mean with lua icon or where it comes from. Does it only happen with coc ? If yes, what exactly is coc doing in that case? If not, please give reproducible steps.
If it only happens with coc I suppose it uses some autocommands that vim-airline does not see, most likely of missing nested.

BTW: does it change, after you move to the windows and then back? e.g. :wincmd w and then :wincmd w?

Updated the post.

some 'coc-extention + server' like coc-rust-analyzer, 'coc-sumneko-lua + lua-language-server' affect the statusline.

I found the 'StatusLineParser' string in

coc-sumneko-lua-data\sumneko-lua-ls\extension\client\node_modules\simple-git\dist\cjs\index.js.map
coc-sumneko-lua-data\sumneko-lua-ls\extension\client\node_modules\simple-git\dist\esm\index.js.map

I don't know if the problem of not being able to distinguish between the individual buffers when displaying the statusline is a structural problem with 'vim-alirline' or the fault of 'coc-extention'.

[chrisbra]

what are those 'StatusLineParser' links?

[xvim64]

what are those 'StatusLineParser' links?

I don't know js, so I suspected something is affecting to the 'statusline'.
so I searched the 'statusline' keyword.
The 'StatusLineParser' is the only keyword that has 'statusline' in 'coc-sumneko-lua-data**'

ps.

I found the cat.
