Facebook Flash Videos Showing Green Screen

Green Screen When Playing Any Flash Video

Symptom:

After updating to the latest flash player version, when  you play any flash video, you get a screen screen with no video but with audio.

Solution:

1. Right click on the flash video, select "Settings".

2. In settings's display tab, uncheck "Enable hardware acceleration".

3. Refresh your flash page, it should start playing.

Note:

You must have the latest graphics drivers installed on your computer too. I've tested this on all 3 browsers of mine: IE, Chrome, and FireFox. All worked fine after applying this setting.
If after performing this steps, it still doesn't work you may refer to Google Chrome's fix to it at HERE.
