It's only been a few days since I configured vim, installed WSL2, etc. Everything was alright, but today was different. I opened vim, and began coding. My code was kind of long so I couldn't see the full code on the screen. When I go up to see the rest of my code, I saw green stripes on almost every line that was empty.
To make it go away I had to type something on it and then erase it. When I was done, I scrolled down to see the other part of my code and there they were again! I googled: "Green stripes on empty space vim" but with no success. I would like to know which vim configuration does that so I can stop it.

<C-l>(control + lower case letter L)? – Martin Tournoij Jul 27 '20 at 16:23<C-l>redraws the screen, so it sounds like a rendering error or the like, rather than a plugin doing this intentionally. I suspect this may be a bug somewhere (but that's really just a guess!) You can try following How do I debug my vimrc file? and see if it's triggered by a specific setting or some such. – Martin Tournoij Jul 27 '20 at 16:36
