I did a zypper dup this morning (12June2019) with 331 updates I think, and Skype video is now reminiscent of "Max Headroom" ... bizarre choppy video that goes back & forth in time in the frames.

This effect occurs with my local camera, Logitech C910, whether I am connected to others or not, as well as the feed from the people I'm communicating with. When the video stream of any source starts, the image is filled with wild colors like a psychedelic test pattern, then the choppy video begins.

I reverted to the previous version of Skype which worked fine this morning before the updates, and it made no difference.

I ran guvcview, and the video was perfect on there. I tried a different USB camera and it behaved exactly the same way.

glxgears runs smoothly. Youtubes are fine. Locally run videos are fine.

Ideas for resolution or learning the cause of the problem very much appreciated. Thank you!
