Hi there,
I just installed ZBrush 4.0 on my MacBook Pro (2.26 GHz Intel Core 2 Duo) and I noticed that when doing a “Init ZBrush” or creating a new document (standard gradient background) the canvas is flickering? This only happens in the gradient area and not anywhere around it… Any ideas?
Thanks!

Update:
After some researching, I found that even new MacBook Pro displays are not perfect. First I took a screen shot of ZBrush and noticed that I still had the same effect, just watching the gradient in another program. I then found this:

I think I will solve this by not using that kind of gradient pattern for my background on my MBP 
Thanks,
Pat
