I use YouTube a lot and it is my go-to website to listen to music and watch interesting videos. However, recently all the YouTube videos I watched just showed me a green screen while the videos were playing. This happened in all the browser including Google Chrome, Opera, Firefox and Internet Explorer 9.
Due to the Green screen (pictured above) I was unable to watch any videos. However, I was still able to listen to the audio. It turns out that the above problem was with a recent update to Adobe Flash player. If you are seeing a similar problem, here are the steps to fix it.
Step 1: Right click on the video player and select Settings from the menu options. Once the options page opens, click on the "Display icon".
Step 2: Uncheck the box next to "Enable hardware acceleration" to disable hardware acceleration for Flash. Once you have done that close the options box and refresh YouTube.
This should help to resolve your issue with the green screen on YouTube. Alternatively, you can also opt-in to YouTube HTML5 player by visiting http://www.youtube.com/html5. However, not all YouTube videos are HTML5 so you might still have to follow the steps listed above to get rid of the Green screen in videos on YouTube.
