I am using Ubuntu 14.10 64bit and the latest version of VLC media player, when I play a video (MP4, MKV AVI etc... it doesn't matter) at the bottom of the screen there is a green line
It isn't an issue with my OS, YouTube, and the default media player work fine. Has anyone else had this issue? and if so is there a fix or is it just a software bug?

This looks similar to the green lines that VLC renderes at the lower or right border when the video stream has an odd resolution. – LiveWireBT Oct 24 '14 at 18:05

Standard 1280x720 in an MKV container. – GhostMotleyX Oct 25 '14 at 16:45

1This may be related to hardware accelerated video decoding and/or rendering. You can try to disable it in the settings in two places: on the “video” panel (called “Overlay video output”) and [on the “input & codecs” panel](http://www.ghacks.net/2013/03/05/how-to-enable-gpu-accelerated-decoding-in-vlc/). – David Foerster Oct 26 '14 at 15:04

Yep, that worked. Thanks. If you post that as an answer I will vote up your answer so you can get reputation – GhostMotleyX Oct 28 '14 at 23:20

Open vlc and then go to preferences > video > select in the output "X11 video output" (you can mess with this to find the one that works best for you).
That's it :P

2It worked. 2022 menu is : Tools >> Preferences >> Video >> Output. Also in my ubuntu 20 fresh intall, the exact option was : X11 Video Output (XCB) – JRichardsz Oct 11 '22 at 01:20

Also you have to reopen the video after saving the preference if that is not obvious. – capn Dec 13 '22 at 01:28
Ctrl-P/Preferences/Video/Output.
Choosing OpenGL GLX Video output (XKB) should solve this problem.
At the same time, that change should also improve appearance of subtitles.
Before:

After:

A good idea might be also:
Tools menu -> Preferences -> Video -> Uncheck "Accelerated Video Output (Overlay") (as stated here.)

I picked `X11 video output (XCB)`. I had a green part appearing at the top of the video, and now it disappeared. Good idea changing this setting. – steoiatsl Aug 17 '22 at 03:26
Open VLC
Go to Tools menu -> Preferences -> Video -> Uncheck 'Use hardware YUV-> RGB Conversons' Restart VLC

2This should be the accepted answer, it fixes the problem without a performance loss. – Robin Clowers Jan 19 '17 at 23:33
Try the following options -
Tools menu –> Preferences –> Video –> Choose OpenGL under Output options –> Restart VLC.
Tools menu -> Preferences -> Video -> Uncheck "Accelerated Video Output (Overlay") -> Restart VLC.

Thank you. I have done the first step, but cannot find "Use hardware YUV>RGB conversions" to uncheck it for the second. So far, the green line has gone but the video is small and in bottom left corner. – Ben Moore Nov 16 '14 at 12:53
-
I have changed the second step accordingly. Try pressing `c` when the video is playing and let me know. – Rohith Madhavan Nov 16 '14 at 12:55

I'm afraid the video is still small and in the bottom left corner. Pressing c changes the shape but not the size. – Ben Moore Nov 16 '14 at 12:57
-
Ok. Instead of OpenGL try OpenGL GLX or something else in the Output options. – Rohith Madhavan Nov 16 '14 at 12:59

Selecting X11 Video Output in Output options may also do the trick. – Rohith Madhavan Nov 16 '14 at 13:10
