Autocomplete+ doesn't work when solargraph is enabled

[aergonaut]

With the atom-solargraph extension enabled, autocomplete+ appears to stop working. No suggestions appear, even for snippets or other terms in the file.

With atom-solargraph disabled, autocomplete+ goes back to normal and starts showing suggestions again.

Pressing ctrl-space or ctrl-alt-o doesn't have any effect.

commandPath is set to /Users/chris/.rbenv/shims/solargraph because I use rbenv.

The extension used to work for me, but I have since switched laptops and reinstalled my tools. I might be missing some customization or other setting.

Ruby version: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin18]
Solargraph gem version: 0.31.3
atom-solargraph version: 0.14.0
Atom : 1.35.1
Electron: 2.0.18
Chrome : 61.0.3163.100
Node : 8.9.3

So does my Atom.

Ruby version: ruby 2.5.0 [Windows 10-x64]
Solargraph gem version: 0.32.1
atom-solargraph version: 0.4.0
Atom : 1.36.0

Is there any logs to help solving this problem? Solargraph works quite well in VSCode.

It takes some seconds after Ruby file opened. It works, but takes a long time to start up.
Another strange behavior, sometimes I enter Enter, but it doesn't complete the word. For example, if I enter Str, String must be the first selection, after Enter is pressed, String is not written down. Sometimes I enter Ctrl+Space, but redundant words are written down. For example, If I enter Str, then Ctrl+Space, StrString is the result. It seems the first time I open a Ruby file will trigger any of the situation ...

I am having this same issue on Ubuntu 18 & Windows 10. Is there a workaround for this?
