Ditto of above post. Performance is much better with this version but I am also seeing the visual glitches a lot more. I am running 10.12.2 beta (16C60b) on a mac Mini 2012 core i7/16gb ram. I have DL3.0 beta installed from "DisplayLink Installer 77739.dmg" and my device is a "Plugable USB3-HDMI-DVI" that uses the DL3500 chipset I believe.
I am attaching a couple of pictures I took with my phone to show the artifacting. Hoping that these visual glitches can be improved...
