WoW - Flickering graphics

[Treesy]

I've been using Keyclone and I have been getting flickering graphics and sometimes abstract graphics when playing.

When in Keyclone I set an account to use CPU 0, I get really bad graphical abstration and flickering graphics.

Is there anyway I can fix this problem? and, what could be the possible cause of this problem? (I dont get the problem when running a single instance of wow).

Can you post your system's specs?

How many monitors are you using?

Does it occur when running 2+ WoWs, but no keyclone?

Hope this is enough
