Bug Description
*PLEASE READ FIRST BEFORE CONSIDERING MAKING A COMMENT*
If you are having an issue and want it addressed, it is most helpful to file a new report. If you were led here by DisplayLink's website, you were led here in error as no useful debugging information has been provided by the original reporter, which is necessary to root cause, and solve the issue he reported. Posting comments about how you think you have the same problem isn't helpful here.
My issues is, after adding a 3rd monitor to Ubuntu 14.04, the mouse flickers (or blinks) when the cursor is on monitors one or two, but not 3.
Monitor 1: 1440 x 900 - Laptop's Native Monitor
Monitor 2: 1920 x 1080 - Laptop's HDMI Port's External Monitor
Monitor 3: 1024 x 768 - SIIG USB 2.0 to VGA Pro Monitor
Here's the video card that feeds my laptop's native monitor, monitor 2 (hdmi).

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
The 3rd Monitor is powered through a Display Link certified SIIG USB 2.0 to VGA Pro adapter (A2H1320X1374 - not sure what this number, but it is a sticker on back of the device):

Sounds like a driver / X issue.
