same issues as beta 1
 

I am still getting the same problem with Beta 2 that i had with 1. Flickering green and pink horizontal lines across entire second display after 1 minute of use. I haven't read anywhere in these forums of this issue but I had the same thing with the last version??

Restarting makes no difference. Also when restarting my screensaver came on even though its off in settings.

I was going to attach an image of this but they do not show up on a screen capture.

I am using - KWORLD USB to DVI UD165

Is this adaptor compatible? If not which ones are please??

Macbook Pro early 2011 2.2 GHz intel core i7
Mountain Lion 10.8.2
Intel HD Graphics 3000 512 MB
AMD Radeon HD 6750M

This sounds like a hardware failure, i.e. either a broken device or cable. Does it work on Windows? Can you take a photo of the corruption when it happens?

Thanks,
Michal

I tried different cables and two different monitors and it made no difference. I dont have a windows computer to test on so I cannot do that. Its only happened since updating to mountain lion.
As I said in original post I cannot send an image because when I screen capture it does not appear in the image but I will take an actual photo of it and upload it.
