I have a little trouble with the plug IRkeystone 2 or 3.
so ... as soon as I apply IRkeystone to a composition, it creates a geometric pattern (fine ... but visible) on the video output. I used it for installation (http://www.straight-disorder.net/ >> ]Panoramix [# 6) with 3 screens / 3 VP + 1 MatroxtripleHead and this plug is almost indispensable ..

Would there be a particular setting of the video card that could solve this problem? or other solution ..?
thank you in advance for the help
