Just curious if anyone else has this issue. I purchased this multi video output device (http://www.amazon.com/gp/product/B00URFBHSM) for when I present at customers who don't have HMI or DP projectors. The past two times I used it the screen flickered horribly in Yosemite. The side of the screen and text gets all "jittery" (hard to put into words). When I rebooted under windows 10 (boot camp), it works perfectly without issues. Any ideas?
