Issue with neovim+alacritty

Hi there! Thanks for the plugin :D

Is there any known issue with alacritty and/or using neovim instead of vim?

It seems to be tracking more or less accurately but with constant intervals (even though I'm not actually doing anything else but using nvim). It seems to track the activity sort of on and off.
I do use a stupid amount of tabs and splits (no tmux, just nvim), so maybe that has something to do with it?

I hope I'm not missing anything here.
