When switching to an invalid file (client.java because its empty, Lsp is complaining) bufferline throws an error.

Auto-session is the session management plugin I use for my neovim setup.
Barbar is the tabline plugin used for showing buffer that are open.
Neotree is a tree plugin.

Auto-session saves all buffers currently being used including Neotree. When restoring, Neotree has an option to clean any invalid neotree buffers from the restore. This makes the previous sessions neotree buffer be deleted.

Not intended behaviour.

Intedended: When restoring from a session, the neotree buffer remains open and continues where it was left off.

The problem with this is now barbar. Barbar has some sort of hook that when a buffer is created, it tries to make it a tab, but Neotree doesn't render in normal buffers so barbar has a fit and an error is thrown when trying to create the tabs from a session restore.

Images:

Neovim config with neotree and barbar open.

Then we quit using :qa and start nvim again.

By the looks of it, barbar is crashing because it can't find a handle that Neotree has removed on its own.

Workaround:

For now, using auto-session, we can add a pre-save command that closes neotree so it doesn't show up in the next session.
Thus neotree won't show when starting a session.

PS: check terminals as this might also be an issue with them.

There seems to be a problem with treesitter and parsing long files with multi-line comments.

Eg:

• nvim-treesitter/nvim-treesitter#5057
• NvChad/NvChad#1415

I've only briefly tested different configs for trying to remove the lag spikes with treesitter. So far removing 'comment' has drastically improved my scrolling in neovim when editing long files with lots of comments.

I'm adding this issue to look back when the performance tanks again due to some reason.

idk why treesitter comment lsp does this.

Disable tree-sitter autocomplete in telescope.

When using the keymap (ctrl + ), autocomplete is activated and shows up in telescope stealing focus from the telescope window.
