I'm using terminal vim with the solarized-light theme for both vim and my terminal. If I try and use for example a dark colour scheme for my terminal a dark border appears around my vim window as shown in the image below.
Is there a setting I can change to remove this border, or reduce its width to 0?
You can't do that from Vim and your terminal emulator doesn't expose an option for that either.
So… use the same background color.
