Recent word suggestion popups that block autocorrect suggestions and other things

I can't figure out what is causing this, but here are a couple screenshots of the most useless and dysfunctional autocorrect I've ever seen.

It's obstructive and doesn't go way when I tap the popup. It suggests some of the most obscure words in the English language and just gets in the way of things. I figure I must have some intrusive app or something.

I have a nexus 6, running Marshmallow. Any ideas what might be causing this?
Much appreciated!

That is odd.
Personally I never liked and never use the stock keyboard. I always use a 3rd party app.
Currently I am using Thumb Keyboard and it is great.
The customization is spectacular.
This is just one of many options.
Just my $.02
