I am not sure the technical term for it, but I am experiencing a rather annoying bug with the little window that appears with auto-predictions.
A few days ago I finally got around to upgrading Sublime to:

I have a 4 monitor setup, with my ST3 setup on an auxiliary screen to the left of the “main” screen. Whenever I type and ST3 comes up with an auto-prediction, this box appears NOT on the screen where ST3 is, but on the main screen.
Is anyone else experiencing this?
