Same problem with two external monitors on ACER Aspire v3-371 notebook running Ubuntu 14.04 LTS (up-to-date) and the newest available DisplayLink driver.
My workaround at the moment: I connect one monitor with the HDMI port of the notebook and the second monitor with the HDMI port of the docking station. The CPU usage drops down and seems to run constantly on 16%!
Sadly I run into the "mouse flickering" problem, which is also a known bug/problem. So on the monitor connected to the internal notebook HDMI port has got problems to display the mouse cursor.
