Similar problem
 

My Asus monitor displays colors fine upon startup, but them sections change colors as the mouse moves around on it. I updated to the most recent driver yesterday and thought the problem was fixed, but it is back today. I am using the DisplayLink_7.7M4.exe driver.

I still do not have a solution, and will have to retry with the next OS reinstall. Out of curiosity, what video driver / computer set-up are you using?
