My first post here. After upgrading to 2016.2 (and reinstalling my crashed laptop), PyCharm seems to be hanging pretty much all the time when typing. I type code, don't get any suggestion popups etc, but text input just hangs for 2-3 seconds. It resumes shortly afterwards but is really irritating. I have tried changing settings (highlighting level set to minimum) and two different Java versions (oracle java 8 and openjdk 9) but the result is the same. When it freezes, it doesn't show any activity in "background tasks" window.
I don't seem to find help by googling. Everything I can find are complete freezes that require a restart. The laptop is a powerful MSI laptop with 16gb of memory and Ubuntu 16.04. This combination used to work absolutely fine until I had to reinstall the laptop from scratch. I must have now an offending component somewhere, but no means locating it. The laptop itself doesn't freeze, just Pycharm.
