Oh wow, doesn’t really even have to do with clicking. It just vanished after a second or so of having opened the editor

Choosing to fold from the command palette also has no effect thereafter.

Darnit. It dies quicker than I can get a screenshot of

Here’s a fold free gutter

Notice there’s nothing where the usual fold icon should be

Looks like this issue: https://github.com/BetterThanTomorrow/calva/issues/2486 Workaround in the issue description. From one of the comments it looks like it stopped working also with nightly builds. Another workaround is to use the previous stable clojure-lsp release.

Thanks @U0ETXRFEW. There seems to be something about the nightly for sure. Backspacing an empty list on the first line throws an error

Just insert a () . remove the opening parentheses, and this pops up

That doesn’t look lsp related, though.

Right. I am not sure what it is, didn’t look at it until this morning

The folding issue should be fixed next clojure-lsp release. Though it will keep working differently than with the indentation setting. The other issue I don’t know what it is, but I can reproduce it. Afaict it only affects that particular situation.
