I'm running 2017.1.4 still and it's been nothing but fast. Either your computer is slow or you have too many enabled language injections or inspections enabled.
It doesn't freeze, but it only starts processing what I typed when I've stopped (i could type a couple of lines fast with a syntax error and it won't point it out until I stop) and I'm on 2016.3.2 lol
Mine doesn't do that. So what I said still applies, however I agree with dktapps, you should upgrade either way.
when you move your minigame from your local dev server to the main test server and it works first try
'When you move your completely working plugin from your local dev server to the main test server and nothing works' My case ^
