How to disable popups about IDE interactions in IntelliJ

How do I disable these popups in IntelliJ that show up after almost each interaction with IDE?

These popups appear if I minimize a tab or start tomcat or execute any code or start debugger, etc. I tried unchecking all options in Preferences > Appearance & Behavior > Notifications but they still appear.

I am using IntelliJ IDEA 2018.2.1 (Ultimate Edition) Build: 182.3911.36

Solution

Looks like you have the Key Promoter Plugin (or, less likely, the Key Promoter X Plugin) installed.

You can disable/uninstall this plugin from Preferences > Plugins.

Here's a screenshot (note the Uninstall button on the right hand side):
