Sublime Text 3.2.1: How do I get rid of these popups as I type?

The popups give context help on whatever I am typing. I find them distracting and they often obscure code I am looking at while I type.

These are my current Sublime Text (syntax specific) settings:

// These settings override both User and Default settings for the JSON syntax
{
    "translate_tabs_to_spaces": true,
    "show_definitions": false,
    "auto_complete_delay": 100,
    "open_files_in_new_window": false,
    "auto_complete_commit_on_tab": true,
}
