I do not think the problem is related to nVidia drivers; the real problem is that whoever created the blur effect seems not a programming genius ...
Personally i would trust a developer more than some nVidia lover or should I say "fanboy". The fact is that nvidia binary driver is far from perfection when you compare it with windows driver, so blaming nvidia driver for that is logical step i believe.
