Gradient Fading - How to avoid stripes?

Hello,

is there a way to get rid of the ugly stripes that appear when you fade in (or out) a quad with a gradient-texture on it? (see attached patch)?

What is the best way to fade in or out an object really slow (> 60 sec) as smooth as possible?

thank you for your help!
