YouTube videos all choppy Has anyone seen this behavior when playing videos in the YouTube app?
I've tried clearing both the cache and data for the app, but it did not help.

Note in the screenshot how the video is all choppy and blocks that are all mixed up. 
It is happening on ALMOST all videos, but every rare one will work fine.

Running on a stock Verizon Galaxy S3.
I had exactly the same problem. The only way I found to 'fix' it was to uninstall all updates back to factory defaults. So far that seems to have done the trick.
