Whenever I come across a page with an embedded YouTube video and press play then the sound will be heard but the video will be blank (a black screen).
The controls work just fine - it's just that I don't have any video.
If I attempt to rotate the phone to landscape, then the video will briefly show just before the screen is rotated and then go back to being black again. Sound will continue to play just fine. If I attempt to rotate the phone back to portrait then the same thing happens again.
This problem occurs in Chrome, but also in any apps where the browser has been embedded (eg. Feedly and Facebook).
My phone is a Samsung Galaxy S3 (i9300) running CM11-20141115-SNAPSHOT-M12-i9300.
Is there any way I can resolve this?
