Screen blur during vertical scrolling
I have a Macbook Pro, which is less than 3 months old, running OS X Yosemite, and I have just noticed that, during vertical scrolling, there is a screen blur which appears in random places.
Clearly, this isn't normal operating conditions, so I was hoping someone might be able to tell me whats going on.
Thanks in advance
