Bug: ram usage spikes when scrolling

[iaurman]

Describe the bug Neovim ram usage spikes when scrolling with Colorizer plugin loaded. This behavior disappears when Colorizer is not loaded.

To Reproduce

1. Using neovim with nvim-colorizer.lua loaded to open a file
2. Open another terminal running htop to monitor the ram usage of this neovim process. At this point it should be 20MB or so.
3. On neovim, use your mouse to scroll
4. You can see on htop that the ram goes up to about 200MB. If the file is long enough and you keep scrolling, it would go up to a few GBs easily and fast. Until it's got terminated by 00ram killer.

Expected behavior Not taking so much ram.

Operating System: Arch Linux x86_64

Neovim Version: NVIM v0.8.2

Colorizer Version: 760e27d 3 months ago
