Same here. Any updates or workarounds? None of the above workarounds works. 
The number of monitors does not matter. I have only two monitors active. The problem still exist. It's about the UGA and two graphic cards. 
For me, browser activities will trigger the mouse cursor flickering problem. And yeah, the flickering only happens in the monitor connected with built-in graphic card, NOT in the monitor connected with UGA.

Title:
  Mouse Flickering after adding 3rd Monitor

Status in xorg package in Ubuntu:
  Confirmed
Status in xorg package in Fedora:
  Unknown

Bug description:
  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).

  lspci | grep 'VGA\|Display'
  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):

  lsusb -tv

      |__ Port 6: Dev 2, If 1, Class=Video, Driver=uvcvideo, 480M

  dmesg
  [    1.688343] usb 2-1: New USB device found, idVendor=17e9, idProduct=02ee
  [    1.688348] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

  [    1.688356] usb 2-1: SerialNumber: 119785

  Additionally, unity-control-center crashes sometimes after I "Restore
  previous settings", after selecting a resolution too high. This
  freezed my laptop, requiring a hard reboot.
