Python3 process starts consuming 20% cpu after creating a split in neovim

[bool3max]

Using neovim 0.3.3, latest version of the plugin installed using vim-plug, latest stable python3 on arch (kernel 4.20.0).

The plugin's python3 process starts consuming around 20% cpu power after switching to another file in neovim (:sp or :vsp can cause this). Below is a htop screenshot showing the plugin's process utilizing 20% cpu:

It stops after neovim itself is terminated.

Likely a python3-neovim bug, I've seen it happen with other plugins. Will take a look regardless.
