Text changes when moving cursor over

Question

I was modifying an email template and I noticed that when moving the cursor over a piece of code it changed.

Here is a screenshot from before:

and after:

Vim version is 7.4 on Ubuntu 16.04. Any idea what would make something like this happen?

This looks like a problem in your terminal emulator. Which terminal are you using? What's the TERM environment variable set to? You can also try following these steps, to make sure it's not a plugin or something in your vimrc. — Martin Tournoij, Commented May 19, 2017 at 15:01

Your terminal window isn't configured to display colors properly.

You can test whether this is the case by disabling color in vim and see if the problem goes away.

Disables color features in vim:

:syntax off
:set nohlsearch
:set t_Co=0

If this fixes it but you want color support, the next step I suggest is to check your terminal emulator and shell configuration for ANSI support.

it displays the colors properly, the photos are from when trying to replicate the behavior and ubuntu probably didn't recognized the code because i named the file test instead of test.php
