How to disable Emacs highlighting whitespace in parenthesis?

Question

In the above screenshot, it can be seen that Emacs highlights the whitespace between parentheses, unless I move my cursor one place to either side.

I have smartparens enabled in my emacs config, but even if I disable them, this problem still persists. I also don't have whitespace-mode enabled.

Any idea what may be causing this?

The relevant part of my config:

(require 'smartparens-config)
(smartparens-global-mode t)
(show-smartparens-global-mode t)

Thanks.

Answer 1

Unfortunately the solution given by Ignacy Moryc, didn't help me, but this one helped:

(setq sp-highlight-pair-overlay nil)

Answer 2

This looks like show-paren-mode

If you have (show-paren-mode t) anywhere in your config file, you might want to remove it. Or you can change the show-paren-style variable value to parenthesis

(setq show-paren-style 'parenthesis)
