Extension creates minute-long lags

[l-t-m-f]

Type: Bug

This extension just by using it creates minute-long freezes when saving Launch.json or Tasks.json.

Nothing to do really, just install and it will be laggy on my pc.

This report was generated following a bisect which identified this extension as the culprit.

I found that this lag, for me, is caused reliably when editing settings.json. I can cause it every save.

However, in my case this lag only happens when I have both LigaturesLimited and VSCodeVim enabled. If I disable either of them, no lag appears. Vim without LL works, LL without Vim works. Together they will cause massive input lag every time the file is saved, and sometimes for other reasons in this file. The mouse still works and text can be selected, but all typing input is buffered until the lag has cleared.

I used bisect as well, but it identified VSCodeVIm as the culprit. However, I think it's an interaction between the two or between two similar plugins. I cannot cause it with just LL enabled.

I'm on MacOS Sonoma, M1 Pro 32GB RAM, no other extensions enabled besides this and Vim.

I experienced this as well, and it eventually led to VS Code errors which prevented all plugins from working.
