Just to confirm geany-lsp is Geany with #3849 and this plugin, all previous versions removed? If so I think I'll just get a new clone [end lazy git user] :-)
It's: 1. Geany 2. This PR 3. [#3850](https://github.com/geany/geany/pull/3850), i.e. including the symbol tree patches. But you can easily simulate https://github.com/geany/geany/pull/3849 by setting `document_symbols_enable=false` 4. https://github.com/geany/geany/pull/3870 5. The patch from https://sourceforge.net/p/scintilla/bugs/2403/ which is merged upstream and we can either get it by updating Scintilla or backporting to Geany (just a few lines of code)
