It's a new local full-line completion model they've been enabling for one language after another in all their IDEs. I too agree that it's a waste of CPU cycles.

It's a new local full-line completion model they've been enabling for one language after another in all their IDEs. I too agree that it's a waste of CPU cycles. The old completion mechanism (a bunch of hardcoded rules plus a bit of machine learning on the side) already was miles ahead of everything else, and with far fewer false-positives. You can disable it by going into 'File | Settings | Plugins' and turning off "Full Line Code Completion".
