Fnaf Main Menu Background Mod

Changes the main menu with The Living Tombstone fnaf music videos. The 5th background is just there as a meme.
There is one issue I don't know how to fix, it's where there's a green and pink lines in the bottom. Any other suggestions you can comment here.

This mod requires GCFScape to view and extract vpk files. You can find it here: https://gamebanana.com/tools/26

Steps to change background:
1) subscribe to mod and run l4d2 so it can load it
2) When it's done loading it, quit the game
3) Go to the addons file in l4d2 by C:/Local Disk/Program Files (x86)/Steam/SteamApps/common/left 4 dead 2/left4dead2/addons/workshop
4) Find the vpk which has the same number as the thumbnail
5) Open GCFScape and move the vpk to it, there you should find the files titled as "l4d2_background01" and such
6) (backup or delete the original files as desired) extract the files to C:\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2\media
7) You're ready now!
