When upgrading from 2.2 on OS X 10.9 this driver still exhibited the problem with 2.2 when writing messages non-stop to the system log but after time seems to have stopped. However the DisplayLinkManager process now uses a constant 50-56% of my CPU even with no apps in the window driven by the dock. This is using a single monitor connected to the display port and a single monitor connected to the USB dock using its HDMI output.
With 10.10 it gets worse. The mouse tracking is horrible and the constant log messages are still present. I can't use 10.10 at the moment with the dock because the mouse pointer is constantly pausing when tracking across all monitors and is super choppy on the displaylink connected monitor.
All in all still very disappointed with DisplayLink drivers. I even had to write my own app that kills the DisplayLinkManager and DisplayLinkUserAgent processes in order to get the dock to work half of the time because I would just get a black screen when I plugged in.
Going to test out one of these docks to see if they are any better
