Second display flicker issues

[nuwanginige]

I just installed Win8.1 and the beta DisplayLink drivers, and now my second monitor is flickering intermittently, sometimes rendering the display unusable. I've followed all of the debugging instructions documented on the site, and attached the diagnostics zip created by the log tool (I ran it in advanced mode while the flickering was happening). Could you please have a look?

I tried a couple of different screencapture methods, but couldn't get a picture. The best I was able to do was the attached picture from my phone.

Please let me know if there's anything further you need on my end.
