The problem of getting a border of green color around the video is common in latest versions of our favorite distributions. Fedora 21 and Ubuntu 14.10 users have reported this problem often.
The source of problem is video output method used by VLC. By default it is set to automatic as you can see below:
- Now change this setting by opening VLC > Preferences > Video
- The recommended output setting is OpenGL GLX, but you can try different output settings, if the former doesn’t work for you.
Now restart VLC to apply the changes.
OpenGL GLX worked best for me on Ubuntu 14.10, it also improved the subtitle rendering and yes solved the green line problem too.
