having a similar issue with very high cpu usage

[baelter]

Same, on ubuntu

Output is

 Locating server…
Booting server...
Checking if /home/xxxx/main.css may be Tailwind-related…
Setting up server…
Listening for messages…
Searching for Tailwind CSS projects in the workspace's folders.

in honesty, this has been an issue for almost 2 years. I remember reporting a similar issue (exactly the same: #593) they closed it and haven't worked on it since. They refer to #444 and close that as well-- made 3 years ago.

I am having similar issue with a higher end pc-- disabling / removing the plugin brought down cpu usage from 50% to 3% lol.

best option here is to remove the plugin as it drastically decreases performance of other VSCode features.

They understand this has been an ongoing issue for years though simply will not work on it.

This is incredibly bizarre. I'm not sure why our LSP would be using that much CPU. Feels like its stuck in an infinite loop or something.

Is there a possibility you (or anyone) can provide the project that is causing this to happen? I don't see this at all ever on our own projects and the nature of an LSP means it is incredibly difficult to debug things like this because they're so environment and project dependent.

[baelter]

I think it happens when I'm not in a tailwind projects, so maybe it's stuck looking for a config file or something, that it will never find. Just guessing :)
