High memory usage - possible leak?

[negz]

I recently started using Neovim, and really like this plugin. Unfortunately I suspect it's causing Neovim to use a lot of memory, and eventually become sluggish.

Here's my configuration: https://github.com/negz/nix/blob/1a26d91/users/negz/nvim/codewindow.lua. I'm using Neovim v0.11 and commit dd70176 of this plugin.

I find that if I:

1. Open nvim at the root of a clone of https://github.com/crossplane/crossplane/
2. Open some ~1,500 line files
3. Toggle my window's open buffer back and forth between two of the large files

I'll see nvim RSS memory increase by 1-2 MB each time I toggle between the buffers. This is true even if there's no changes since last time I viewed the buffer. The memory usage doesn't seem to drop if I :bdelete a buffer.

I tested primarily by toggling between these two files:

• https://github.com/crossplane/crossplane/blob/db0f2c61/apis/apiextensions/fn/proto/v1/run_function.pb.go (~1,650 lines)
• https://github.com/crossplane/crossplane/blob/db0f2c61/internal/controller/apiextensions/composite/reconciler_test.go (~1,500 lines)

I'm unsure if that could be the case, but does this memory usage ever decrease after a while? I could imagine it being garbage collection
