Safari video's no image but sound
Hi all.
I'm using a MacBook Air and Safari, all latest updates done as requested by the system.
Since a couple of days, I can't view any video's anymore in Safari (youtube, news sites, facebook): instead of the image, I either get a black square, or sometimes I get a distorted, glitchy image of some random colour patterns.
However, I still hear the sound fine.
Can anyone tell me how to solve this?
Thanks!
MacBook Air, OS X Mountain Lion (10.8)
